Classify the above into (a) hydrolysis, (b) redox and (c) hydration reactions.

Best Answer

Answer: . (i) PbS(s) + H2O2(aq) → PbSO4(s) + H2O(l)

H2O2 is acting as an oxidizing agent in the reaction. Hence, it is a redox reaction. 

(ii)  (aq) + 5H2O2(g) + 6H+(aq) → 2Mn+2(aq) + 8H2O(l) + 5O2(g)

H2O2(aq) is acting as a reducing agent in the acidic medium, thereby oxidizing  (aq)

Hence, the given reaction is a redox reaction.

(iii) CaO(s) + H2O2(g) → Ca(OH)2(aq)

The reactions in which a compound reacts with water to produce other compounds are called hydrolysis reactions. The given reaction is hydrolysis.

(iv) AlCl3(g) + 3H2O(l) → Al2O3(s) + 6HCl(aq)

The reactions in which a compound reacts with water to produce other compounds are called

hydrolysis reactions. The given reaction represents hydrolysis of AICl3

(v)  Ca3N2(s) + 6H2O(l) → 3Ca(OH)2(aq) + 2NH3(g)

The reactions in which a compound reacts with water to produce other compounds are called

hydrolysis reactions. The given reaction represents hydrolysis of Ca3N2.
