Question

Complete the following chemical reactions. 

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

Answer 1

(i) 

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

(ii) H₂O_2(aq) is acting as a reducing agent in the acidic medium, thereby oxidizing MnO₄^-_(aq)

Hence, the given reaction is a redox reaction. 

(iii)

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

(iv) 

The reactions in which a compound reacts with water to produce other compounds are called hydrolysis reactions. The given reaction represents hydrolysis of AlCl₃. 

(v) 

The reactions in which a compound reacts with water to produce other compounds are called hydrolysis reactions. The given reaction represents hydrolysis of Ca₃N₂.
