Tetraoxosulphate (VI) acid, also known as sulfuric acid, is a strong acid that can burn the skin upon contact.
The reason it burns the skin is due to its ability to react with and destroy the proteins and lipids that make up our skin. This happens through a process called dehydration, where sulfuric acid removes water molecules from the skin, causing it to dry out and become damaged.
Furthermore, sulfuric acid is highly exothermic, which means it releases a large amount of heat when it reacts with other substances. This can also contribute to the burning sensation and damage to the skin.
Therefore, the correct answer is "Dehydration".
