Question

11. Identify the compound X on the basis of the reactions given below.
+ Zn
A) + H2(g)
+ HCI
B) +
H,
Compound
'X'
+ CH,COOH
H,O​

Answer 1

Answer:

Explanation:

Since in first reaction there is liberation of hydrogen gas on reaction with X. Metals liberate htdrogen gas on reaction with bases. Also in second reaction X react with acid to form water and B. Since acid react with base. So, X is a base. Most common base is Sodium hydroxide.

The compound X is sodium hydroxide.

1. Reaction:

NaOH + Zn → Na2ZnO2 + H2

Hence, compound A is sodium zincate Na2ZnO2

2. Reaction:

NaOH + HCl → NaCl + H2O

Hence, compound B is sodium chloride NaCl

3. Reaction 

NaOH + CH3COOH → CH3COONa + H2O

Hence, compound C is sodium acetate.
