Among the many workss in Ontario where sulphuric acid is

produced, there are three major works locations that should

be noted on history of their greater size. These are: ( 1 )

Inco. & # 8211 ; Sudbury, ( 2 ) Noranda Mines Ltd. & # 8211 ; Welland, and ( 3 ) Sulfide & # 8211 ; Ontario

There are a figure of factors which govern the location

of each fabrication works. Some of these factors that have

to be considered when make up one’s minding the location of a Sulfuric Acid works are:

a. Whether there is ready entree to raw stuffs ;

B. Whether the location is near to major transit paths ;

c. Whether there is a suited work force in the country for

works building and operation ;

d. Whether there is sufficient energy resources readily available ;

e. Whether or non the chemical works can transport out its

operation without any unacceptable harm to the environment.

Listed above are the basic decision making factors that govern

the location of a works. The followers will explicate in

greater item why these factors should be considered.1 ) Raw Materials

The works needs to be near to the natural stuffs that

are involved in the production of sulphuric acid such as

S, lead, Cu, Zn sulphides, etc..2 ) Transportation system

A maker must see propinquity to transpor-

tation paths and the location of both the beginning of natural

stuffs and the market for the merchandise. The natural

stuffs have to be transported to the works, and the

concluding merchandise must be transported to the client or

distributer. Economic pros and cons must besides be thought

approximately. For illustration, must sulfuric workss are located

near the market because it costs more to transport

sulphuric acid than the chief natural stuffs, S.

Elaborate committee cogent evidence container are required for the

transit of sulphuric acid while S can be much

more easy transported by truck or railroad auto.

3 ) Human Resources For a sulphuric acid works to run, a

big work force will evidently be required. The works must

employ chemists, technicians, decision makers, computing machine

operators, and people in gross revenues and selling. A big figure

of workers will besides be required for the day-to-day operation of

the works. A work force of this diverseness is hence likely

to be found merely near major Centres of population.4 ) Energy Demands

Large sums of energy will besides be required for the

production of many industrial chemicals. Therefore, propinquity

to a plentiful supply of energy is frequently a finding

factor in make up one’s minding the works & # 8217 ; s location. 5 ) Environmental Concerns

Most significantly, nevertheless, concerns about the

environment must be carefully taken into consideration.

The chemical reaction of altering S and other

substances to sulfuric acerb consequences in the formation of

other substances like S dioxide. This causes acid

rain. Therefore, there is a large job about sulfuric

workss doing harm to our environment as the works is

a beginning of S emanation taking to that of acerb rain.6 ) Water Supplies

Still another factor is the intimacy of the location

of the workss to H2O supplies as many fabrication

workss use H2O for chilling intents.

In add-on to these factors, these inquiries must besides

be answered: Is land available near the proposed site at a

sensible cost? Is the clime of the country suited? Are

the general life conditions in the country suitable for the

people involved who will be relocating in the country? Is at that place

any suggestions offered by authoritiess to turn up in a peculiar part?

The concluding determination on where the sulphuric acid works

truly involves a careful scrutiny and a via media among

all of the factors that have been discussed above.Producing Sulfuric Acid

Sulphuric acid is produced by two chief procedures & # 8211 ;

the chamber procedure and the contact procedure.

The contact procedure is the current procedure being used to

green goods sulphuric acid. In the contact procedure, a purified

dry gas mixture incorporating 7-10 % S dioxide and 11-14 %

O is passed through a preheater to a steel reactor

incorporating a Pt or V peroxide accelerator. The

accelerator promotes the oxidization of S dioxide to

trioxide. This so reacts with H2O to bring forth sulphuric

acid. In pattern, sulfur trioxide reacts non with pure

H2O but with recycled sulphuric acid.The reactions are: 2SO2 + O2 & # 8211 ; * 2SO3

SO3 + H2O & # 8211 ; * H2SO4 The merchandise of the contact workss is 98-100 % acid. This

can either be diluted to take down concentrations or made

stronger with sulfur trioxide to give oleums. For the

procedure, the beginnings of S dioxide may be produced from

pure S, from fool’s gold, recovered from smelter operations

or by oxidization of H sulphide recovered from the

purification of H2O gas, refinery gas, natural gas and other fuels.

Battery Acid Industry Many industries depend on sulphuric acid. Among these

industries is the battery acid industry.

The electric battery or cell green goodss power by agencies of

a chemical reaction. A battery can be primary or secondary.

All batteries, primary or secondary, work as a consequence of a

chemical reaction. This reaction produces an electric

current because the atoms of which chemical elements are

made, are held together by electrical forces when they react to organize compounds.

A battery cell consists of three basic parts ; a

positively charged electrode, called the cathode, a

negatively charged electrode, called the anode, and a

chemical substance, called an electrolyte, in which the

electrodes are immersed. In either a moisture or dry cell,

sufficient liquid must be present to let the chemical reactions to take topographic point.

Electricity is generated in cells because when any of

these chemical substances is dissolved in H2O, its

molecules break up and go electrically charged ions.

Sulphuric acid is a good illustration. Sulfuric acid, H2SO4, has

molecules of which consist of two atoms of H, one of

S and four O. When dissolved in H2O, the

molecules split into three parts, the two atoms of H

separate and in the procedure each loses an negatron, going

a positively charged ion ( H+ ) . The sulfur atom and the four

atoms of O remain together as a sulphate group ( SO4 ) , and

get the two negatrons lost by T

he hydrogen atoms, therefore

going negatively charged ( SO4 & # 8211 ; ) . These groups can

combine with others of opposite charge to organize other compounds.

The lead-acid cell uses sulphuric acid as the

electrolyte. The lead-acid storage battery is the most

common secondary battery used today, and is typical of those

used in cars. The followers will depict both the

bear downing and dispatching stage of the lead-storage battery

and how sulphuric acid, as the electrolyte, is used in the

procedure. The lead storage battery consists of two electrodes

or home bases, which are made of lead and lead peroxide and are

immersed in an electrolytic solution of sulphuric acid. The

lead is the anode and the lead peroxide is the cathode. When

the battery is used, both electrodes are converted to take

sulphate by the undermentioned procedure. At the sulphate ion that is

nowadays in the solution from the sulphuric acid. At the

cathode, meanwhile, the lead peroxide accepts two negatrons

and releases the O ; lead oxide is formed foremost, and so

lead joins the sulfate ion to organize lead sulphate. At the same

clip, four H ions released from the acid join the

O released from the lead peroxide to organize H2O. When

all the sulphuric acid is used up, the battery is & # 8220 ; discharged & # 8221 ;

produces no current. The battery can be recharged by go throughing

the current through it in the opposite way. This

procedure reverses all the old reactions and signifiers lead at

the anode and lead peroxide at the cathode.Proposed Problem

I ) The concentration of sulphuric acid is 0.0443 mol/L.

The pH is: No. mol of H ions = 0.0443 mol/L x 2

= 0.0886 mol/L hydrogen ions pH = & # 8211 ; log [ H ]

= & # 8211 ; log ( 0.0886 ) = & # 8211 ; ( -1.0525 ) = 1.05 Therefore, pH is 1.05.

two ) The sum of base needed to neutralize the lake H2O is:

volume of lake = 2000m ten 800m x 50m

= 800,000,000 M3 or 8 & # 215 ; 108 M3

since 1m3=1000L, hence 8 & # 215 ; 1011 L

0.0443 mol/L x 8 & # 215 ; 1011 = 3.54 ten 1010 mol of H2SO4 in H2O

# mol NaOH = 3.54 ten 1010 mol H2SO4 x 2 mol NaOH

1 mol H2SO4

= 7.08 ten 1010 mol of NaOH needed

Mass of NaOH = 7.08 ten 1010 mol NaOH x 40 g NaOH

1 mol NaOH

= 2.83 ten 1012 g NaOH or 2.83 ten 109 kilograms NaOH

Therefore a sum of 2.83 ten 1012 g of NaOH is needed to

neutralize the lake water.iii ) The usage of Na hydrated oxide versus limestone to

neutralize the lake H2O:

Sodium hydrated oxide: Sodium hydrated oxide produces H2O when

responding with an acid, it besides dissolves in H2O quite

readily. When utilizing Na hydrated oxide to neutralize a lake,

there may be several jobs. One job is that when

Na hydrated oxide dissolves in H2O, it gives off heat and

this may harm aquatic life beings. Besides this, vast

sums of Na hydrated oxide is required to neutralize a lake

hence big sums of this substance which is caustic

will hold to be transported. This is a great hazard to the

environment if a spill was to happen.

The undermentioned equation shows that H2O is produced when

utilizing Na hydroxide.2NaOH + H2SO4 & # 8211 ; * Na2 SO4 + 2H2O

Limestone: Another manner to neutralize a lake is by

liming. Birdliming of lakes must be done with considerable

cautiousness and with an consciousness that the aquatic ecosystem

will non be restored to its original pre-acidic province even

though the pH of H2O may hold returned to more normal

degrees. When limestone dissolves in H2O it produces C

dioxide. This could be a job since a higher content of

C dioxide would intend a lowered O content particularly

when much algae growing is present. As a consequence, fish and

other beings may endure. Limestone besides does non fade out

every bit readily as Na hydrated oxide therefore taking a longer period of

clip to respond with sulphuric acid to neutralize the lake. The

equation for the neutralisation utilizing limestone is as follows:

Ca CO3 + H2SO4 & # 8211 ; * CaSO4 + H2O.

four ) The consequence of the Acid or inordinate Base on the works and carnal life:

You will likely happen that there aren & # 8217 ; t many aquatic

populating beings in Waterss that are overly basic or

acidic. A high acidic or basic content in lakes kill fishes

and other aquatic species. Drawn-out exposure to acidic or

overly basic conditions can take to generative failure

and morphological aberrance of fish. A lowered pH tends to

neutralize toxic metals. The accretion of such metals in

fish contaminates nutrient ironss of which we are a portion as these

metals can do fish unfit for human ingestion.

Acidification of a lake causes a decrease of the production

of phytoplankton ( which is a primary manufacturer ) every bit good as in

the productiveness of the growing of many other aquatic workss.

In acidic conditions, zooplankton species will likely

becompletely eliminated. In add-on, bacterial

decomposition of dead affair is earnestly retarded in

acidified lake Waterss. Other effects of acidic conditions

arean overfertilization of algae and other microscopic works

lifecausing algae blooms. Giantism of these consumes

rapidly most of the O in H2O therefore doing other life

signifiers to decease from oxygen famishment.

When there are inordinate base or acid in Waterss, non

merely do aquatic beings get affected but animate beings who depend

on aquatic workss to last will hunger excessively, since few

aquatic workss survive in such conditions. Therefore each

being in the aquatic ecosystem is effected by inordinate

basic or acidic conditions because anything impacting one

being will impact the nutrient concatenation, directing reverberations

throughout the full ecosystem.

V ) The factors that govern this works & # 8217 ; s location, if this

works employs 40 % of the towns people:

The major factors that would regulate this works & # 8217 ; s

location would be whether there is ready entree to raw

stuffs ; whether the location is near to major

transit paths ; whether energy resources are readily

available and if there is an equal H2O supply in the

country. Since this works would use 40 % of the towns people,

the works should be near to the town while still far plenty

so that in instance of any escape of the works, the town will be

within a safe distance of being badly affected. The

factor of whether the general life conditions in the country

are suited for the workers should besides be considered every bit good.
