Oxidising agent
Reason — Oxidising agents are substances which add oxygen atoms to others compounds or remove hydrogen atoms from others compounds. Sulphuric acid accepts electrons and donates oxygen atoms to sulphur, leading to the formation of SO2 and water (H2O). Thus, sulphuric acid acts as an oxidising agent.
