Sulphuric Acid Formula


Sulphuric acid is the most common acid that is used in various chemical experiments. It is a strong inorganic acid. The chemical formula of sulphuric acid is H2SO4. The molecular formula of sulphuric acid has 2 hydrogen atoms, 1 sulphur atom, and 4 oxygen atoms. The basic concepts related to sulfuric acid, sulfuric acid formula, sulphuric acid molecular formula, the formula of dilute sulphuric acid, structure, chemical properties, and uses of acid, are discussed here, for your reference. 

Molecular Formula of Sulfuric Acid

As we discussed above, the sulphuric acid molecular formula is H2SO4. It has one Hydrogen atom, one sulphur, and four oxygen atoms attached to the sulphur atom. Its molecular weight is 98.079 g/mol. According to the VSEPR Theory, They are arranged in such a way that there is minimum repulsion between lone pairs and bond pairs. It is an oxoacid of sulfur. Two oxygen atoms are attached to the sulphur through the double bonds. Two hydroxyl groups are attached via single bonds. The structure of Sulphuric acid is shown below:

As we can see in the structure, There are two hydrogen atoms attached to the Oxygen atoms. These two hydrogen atoms are mobilizable. Which means they can be removed easily. So, It is a diprotic acid. This is the reason for sulphuric acid being the strongest inorganic acid.

Concentrated Sulphuric acid is corrosive and extremely harmful. So, water is mixed to it to lower the concentration. This is known as dilute sulphuric acid. Dilute sulfuric acid formula has the same formula as Concentrated acid. It only differs in concentration. 

Preparation of Sulphuric Acid:

When one mole of Sulphur trioxide is made to react with water, One mole of sulphuric acid is formed. This is the commercial method known as the Contact process. Vanadium Oxide is used as a catalyst in this reaction.

SO3 + H2O→ H2SO4

Uses of Sulphuric Acid

It is extensively used in laboratories, petroleum refineries, Wastewater processing. It is used in the formation of numerous compounds that are industrially beneficial. It is used in dyes, paints, explosives, and detergents. It is also used as an electrolyte in electrochemical cells and batteries.


So, here we learned the formula of Sulphuric Acid, its structure, preparation, and common uses. The contact process is used to prepare this acid in the laboratories. Sulphuric acid is a strong acid, and it is widely used in laboratories for the syntheses of various compounds. Hence, it is one of the most fundamental topics to learn, in Chemistry.

FAQs (Frequently Asked Questions)

1. Why Sulphuric Acid is Known as the King of Chemicals?

Answer: Sulphuric acid is known as the king of chemicals because it is among the most common acids and is used in a huge number of chemical preparations.
