Identify the substances which are oxidized and the substances that are reducedin the following reactions:

(i) H2 (g) + Cl2 (g) ⎯⎯→ 2HCl (g).

Ans: – The element of the upper reaction H2 is oxidized and Cl2 is reduced and make the compound hydrogen chloride.

 

(ii) H2 (g) + CuO (s) ⎯⎯→ Cu (s) + H2O (l).

Ans: – The CuO is reduced to copper and the H2 is oxidized and became water after this reaction.

 

(iii) Zn (s) + 2AgNO3 (aq) ⎯⎯→ Zn (NO3)2 (aq) + 2Ag (s).

 

Ans: – The Zn after oxidation make the compound zinc nitrates and the silver nitrate after the reduction convert to silver.
