Question

Study the given chemical equations.

(i). H2S + 12 →S + 2HI
(ii). MnO2 + 4HCl → MnCl2 + 2H2O + Cl2

Choose the correct statements about the given chemical equations.
(A) Only I is a redox reaction.
(B) Only II is a redox reaction.
(C) H S is the reducing agent in I while HCl is the oxidizing agent in II.
(D) Iz is the oxidising agent in I, while MnO2 is the oxidising agent in II.

​

Answer 1

Answer:

The given equation is

H2S + Cl2 → S + 2HCl

(1) Oxidized substance

Answer: H2S

By losing hydrogen atoms, H2S is oxidized to form to S.

(2) Reduced substance

Answer: Cl2

By obtaining hydrogen atoms, Cl2 is reduced to HCl

(3) The oxidizing agent

Answer: Cl2

The reduced substance is called an oxidizing agent. Cl2 is, therefore, an oxidizing agent.

(4) The reducing agent.

Answer: H2S

The oxidized substance is called a reduction agent. Therefore, the reduction agent is H2S.
