Concentrated sulfuric acid is extremely corrosive and dangerous
Concentrated sulfuric acid is extremely corrosive and dangerous. Therefore, water is added to dilute the concentration. This is called dilute sulfuric acid. Dilute sulfuric acid has the same molecular formula as concentrated acid. It only varies in concentration. This powerful chemical reacts strongly with the water, generating a lot of heat. Therefore, H2SO4 should never be mixed with water.
