We will first start by addressing the question of what is sulphuric acid. Well, sulphuric acid is basically an oxidizing agent, a strong mineral acid, and a dehydrating agent. Sulphuric acid has the chemical formula H 2 SO 4. The acid is a colourless liquid. It is soluble in water and generally releases heat on contact.
