Sulfuric acid

You may have had many sulfuric acid experiments. Didn't you So, has it ever been put in water? no! never ever! but why? Let's find out In the next section, we will read all about sulfuric acid and its properties. Then we will look at its use. So let's start with what it is.

What is sulfuric acid?

Sulfuric acid, also spelled sulfuric acid or H2SO4, is an odorless, colorless, oily liquid. Also, it is very corrosive. Another name for it is the Isle of Wight. Due to its wide applications, it is called the 'King of Chemicals'. Furthermore, we can find it in both shared and independent situations.

The process of preparation of sulfuric acid

In general, there are two techniques for industrial production of sulfuric acid. They are:

Lead chamber operation

Contact process

Now let's look at these processes in detail.

1) Contact process

There are three main stages in the communication process.

Step-I: Production of Sulfur Dioxide

Sulfur dioxide is produced by heating sulfur or sulfide metals. For example, iron pirates in excess of air.

S (sulfur) + O2 (oxygen) + Δ (heating) → SO2 (sulfur dioxide)

4FeS (iron pyrites) + 7O2 (oxygen) + Δ (heating) → 2Fe2O3 (ferric oxide) + 4SO2 (sulfur dioxide)

Step-II: Formation of Sulfur Trixide

Sulfur dioxide is then oxidized with atmospheric oxygen in sulfur trioxide using V2O5 as a catalyst.

2SO2 (sulfur dioxide) + O2 (oxygen) + V2O5 (catalyst); SO3 (sulfur trioxide)

Step-III: Converting Sulfur Trixide to Sulfuric Acid

Then, sulfur trioxide is broken down into 98% sulfuric acid to provide oleum. Another name for oleum is pyrosulfuric acid. The oleum is then diluted with water to give the desired concentration of sulfuric acid.

SO3 (sulfur trioxide) + H2SO4 (sulfuric acid-98%); H2S2O7 (pyrosulfuric acid / oleum)

H2S2O7 (Pyrosulfuric acid / Oleum) + H2O (Dilution) → 2H2SO4 (sulfuric acid)

2) Lead chamber process

Lead chamber operation is one of the most common manufacturing techniques. This results in about 50-60 B grade acids. In this process, we use wet SO2 in the presence of nitrogen oxides. As a result, it oxidizes with oxygen in the air and forms sulfur trioxide. This is how the reaction is expressed.

2SO2 + O2 → 2SO3

Sulfur trioxide is then made to react with water to obtain H2SO4. This is how the reaction is expressed.

SO3 + H2O → H2SO4

Physical properties of sulfuric acid

Sulfuric acid is a thick, colorless and oily liquid.

Its specific gravity is 1.84 at 298 K.

The boiling point of acid is 611 K. The boiling point and thickness of this chemical is due to hydrogen bonding.

This strong chemical reacts with water which releases a lot of heat. That way, you should never add water to H2SO4. Instead, you should add the acid to the water, slowly, stirring appropriately.

Chemical properties of sulfuric acid

Sulfuric acid is a strong diabetic acid. In addition, it occurs in water solution in two stages, diprotic and ionises.

This chemical is highly corrosive, reactive and soluble in water. It has high oxidizing power and thus acts as a strong oxidizing agent.

There are very few fluctuations. Because of this, it plays a role in the production of more volatile acids than their comparable salts.

Concentrated sulfuric acid is a very strong dehydration agent. Thus this chemical is used to dry many wet gases which do not react with acids.

It also draws water from natural compounds like starch.

Because it is a good oxidizing agent, it can oxidize non-metals as well as metals. In addition, it reduces sulfur dioxide itself.

Some common reactions to sulfuric acid

Hot concentrated sulfuric acid oxidizes copper to copper sulfate.

Cu + 2H2SO4 → CuSO4 + SO2 + H2O

Concentrated sulfuric acid gives hydrogen chloride from sodium chloride. In addition, it releases hydrogen fluoride from calcium fluoride.

CaF2 + H2SO4 → CaSO4 + 2HF

It burns glucose, sugar and starch into carbon.

C12H22O11 + (H2SO4) → 12C + 11H2O

Example solved for you

Question: Write the basic uses of sulfuric acid.

Answer: The uses of sulfuric acid are:

It is a common chemical in the preparation of fertilizers. For example ammonium sulfate and superphosphate.

We use it to make colors, shades and colors.

It is a common chemical in the manufacture of explosives. For example, TNT.

Other essential chemicals require the presence of sulfuric acid. Without sulfuric acid, we can't get this chemical. For example hydrochloric, phosphoric and nitric acid. It is also essential for sodium carbonate.

We use it as part of petroleum refining.

It acts as a pickling agent.

It is common as chemical laboratory agent, dehydration agent and oxidizing agent.
