Is H2SO4 A Strong Acid

Is H2SO4 A Strong Acid? but first learn about what is H2SO4? H2SO4 is called Sulfuric acid. Sulfuric can also be spelled as Sulphuric. Sulfuric acid is one of the most common acids in the world. It is also called oil of vitriol, hydrogen sulfate, colorless and corrosive liquid. Sulfuric acid (H2SO4) is formed by the reaction of water with sulfur trioxide. Sulfuric acid (H2SO4) is a dark brown colorless liquid. 

It’s an extremely useful substance and can be found in many different industries, including making paper, glass, soap, textiles, dyes, and plastics. It has many uses, such as removing paint from metal, dissolving stone, and purifying water.

In H2SO4, H denotes Hydrogen, S denotes Sulfur and O denotes Oxygen. H2SO4 completes with two atoms of hydrogen, one atom of sulfur, and four atoms of oxygen.

One thing sulfuric acid can’t do is dissolve itself. This is because it becomes a very strong acid when it mixes with water, which means that if you drop sulfuric acid into water, it will form the ionized compounds H3O+ and HSO4−. This compound is also known as “hydronium” and “sulfate”.

Physical Properties of Sulfuric Acid(H2SO4)?

There are many physical properties of Sulfuric acid (H2SO4) in which some of the properties are given below:

  • Sulfuric acid (H2SO4) is Colorless, Odorless, and an oily fluid liquid
  • Sulfuric acid is an inorganic acid that is highly toxic and corrosive material.
  • H2SO4 is a thick liquid. The hydrogen bonding in the sulfuric acid makes it thick.
  • The density of sulfuric acid (H2SO4) is 1.8302 g/cm3 and molar mass is 98.079 g/mol.
  • The boiling point of the sulfuric acid is 337 °C and the melting point of sulfuric acid is 10 °C.
  • It is highly soluble in water and produces a lot of heat.

Chemical Properties of Sulfuric Acid (H2SO4)

There are many chemical properties of Sulfuric acid (H2SO4) in which some of the main properties are given below:

  • Sulfuric acid (H2SO4) is a strong acid that is highly soluble in water.
  • Sulfuric acid (H2SO4) is one of the strong oxidizing chemical.
  • Sulfuric acid will release hydrogen gas as it reacts with metals. This gas is flammable and may explode under pressure.
  • Sulfuric acid reacts exothermically with chemical bases (for example hydroxides) to form salts.
  • Sulfuric acid or ‘oil of vitriol’ is a colorless, powdered, and odorless chemical. It is a strong dibasic acid, diprotic, and ionizes in two stages in the aqueous solution. It reacts in many ways depending on the temperature and concentration.

Uses of sulfuric acid(H2SO4)

sulfuric acid(H2SO4) is a very common acid in the world. It’s an extremely useful substance and can be found in many different industries. some of the uses of sulfuric acid are given below:

  • It is used in the production of many substances such as fertilizers, drugs, dyes, detergents, petroleum products, pigments, etc.
  • Sulfuric acid is also used in the manufacture of explosives, antifreeze, and electric batteries
  • In the oil industry sulfuric acid is used to dissolve limestone from wells.
  • In the petroleum industry in both oil refineries and pipelines, Sulfuric Acid is used in high concentrations to wash impurities, like Asphaltenes, out of gasoline and other refinery products.
  • In the pharmaceutical industry, sulfuric acid is used to manufacture aspirin.
  • Sulfuric acid is also used in mine drainage neutralization as an alkaline agent.
  • It is also used in lead storage batteries of electric vehicles and automobiles.
  • Sulfuric acid is used in oil refineries and for the acidizing of rocks.
  • It is used in the lab testing analysis.
  • It is also used in making papers, perfumes, medicines, printing, potato farming, skin ointments, etc. 
  • Sulfuric acid is a strong, corrosive, and dangerous mineral. Its distinctive nature and components saw it broadly utilized for numerous reactions, for example, in alloys, tanning fabrics, dyes, bug sprays, etc.

What is the atomicity of H2SO4?

Atomicity means the total number of atoms in a molecule of a compound. H2SO4 made with 2 atoms of Hydrogen, 1 atom of Sulfur, and 4 atoms of Oxygen. The total number of atoms present in H2SO4 is 7. So, the atomicity of Sulfuric acid (H2SO4) is 7.

Is H2SO4 harmful to humans?

Sulfuric acid is a very strong chemical that should be handled with extreme care. It is corrosive to the skin, eyes, and lungs. It can cause severe burns to the skin and eyes. If swallowed, it can burn holes in the stomach or esophagus. Inhaling sulfuric acid fumes or mist may irritate air passages of the nose, throat, and lungs causing coughing and wheezing.

What is the specific gravity of sulfuric acid?

Specific gravity is one of the main physical property of sulfuric acid. This is the average mass of one molecule divided by the mass of a single molecule. If you divide the mass of a molecule by the mass of a single molecule, the mass of the molecules in a large quantity will cancel out. As a result, the average mass of a large quantity of sulfuric acid is the same as the mass of a single molecule. The specific gravity of sulfuric acid is 1.835.

Why is H2SO4 a strong acid?

In chemistry, a strong acid is an acid that is completely dissociated in an aqueous solution. When H2SO4 reacts with water it gets dissolved in water, it completely dissociates into hydronium (H+) and sulfate (HSO4-) ions. There is no undissociated H2SO4 molecule left in the solution. Therefore, H2SO4 called a strong acid.


H2SO4 + H2O → H3O+ + HSO−4   

HSO−4 + H2O → H3O+ + SO2−4   


Who derived H2SO4?

Jabir ibn Hayyan a Muslim chemist derived H2SO4 in the 8th century.

How many atoms are in H2SO4?

There are 7 atoms in H2SO4. H2SO4 makes up 2 atoms of hydrogen, one atom of sulfur, and 4 atoms of oxygen.

Is sulfuric acid used in drugs?

 Yes, Sulfuric acid is used in drugs like Pentosan polysulfate.

How many ions are in H2SO4?

There are two ions in H2SO4. One is a sulfate ion (anion) and the second is a hydrogen ion(cation).
