`SO_(2)+2H_(2)Srarr3S+2H_(2)O`
the substance oxidised is

Text Solution

Verified by Experts

(i) Here, `SO_(2)` is changing into S. This is the removal of oxygen from `SO_(2).` By definition, the removal of oxygen is called reduction. Thus, `SO_(2)` is being reduced to S. So, the substance being oxidised is hydrogen sulphide, `H_(2)S.`
(ii) `H_(2)S` is changing into S. Thus is the removal of hydrogen from `H_(2)S.` By defination, the removal of hydrogen is known as oxidation. Thus, `H_(2)S` is being oxidised to S. So, the substance being oxidised is hydrogen sulphide, `H_(2)S.`
