Select the oxidising agent for the following reaction: $H_2S + I_2 \rightarrow 2HI + S$ >"
Correct Answer: (a) I2
Explanation: In the above-mentioned reaction, Hydrogen sulphide is being oxidized to sulphur (The removal of hydrogen is known as oxidation). As iodine is removing the hydrogen from H2 S, hence, iodine is the oxidizing agent.
