Question

$H_{2}S{O}_4$ has very high corrosive action on skin because:

• A. It reacts with proteins
• B. It acts as an reducing agent
• C. It acts as a dehydrating agent
• D. It acts as an oxidising agent and absorption of water is highly exothermic

Answer 1

The correct option is D It acts as an oxidising agent and absorption of water is highly exothermic

$H_{2}S{O}_4$ acts as oxidising agent as $S$ is in $+6$ oxidation state, so can go to lower oxidation state. $H_{2}S{O}_4$ absorbs water and releases high amount of energy hence, it is an exothermic reaction.
