Question

Consider the following chemical reaction and answer the questions 4 that follow:
H2(g) + Cl2(g) 2 HCl(g)
i. Which substance has been oxidized and why?
ii. Which substance has been reduced and why?
iii. Which substance is acting as oxidizing agent and why?
iv. Which substance is acting as reducing agent and why?

Answer 1

Explanation:

i). Answer :- The sulfur changes from an ion to an atom so it can covalently bond with the oxygen, so to go from a 2- ion to a neutral atom it must have lost electrons, so the sulfur is oxidised..

ii). Answer :- in D) reaction underlined substance undergoes reduction.

iii). Answer :- Sulfur is called the oxidizing agent. The zinc causes the sulfur to gain electrons and become reduced and so the zinc is called the reducing agent. The oxidizing agent is a substance that causes oxidation by accepting electrons; therefore, its oxidation state decreases.

iv). Answer :- Donate electrons substance is acting as reducing agent ..
