Answer 1

Answer 2: 0.01M AcOH, 0.01M NH4Cl, 0.01M NH3 are assigned here as weak electrolytes, of which,

Weak Acids: 0.01M AcOH, 0.01M NH₄Cl.

Weak Bases: 0.01M NH₃.

Corresponding equilibrium chemical quation is,

1) AcOH + H₂O $\rightleftharpoons$ AcO^- (aq) + H₃O⁺ (aq)

2) NH₄Cl (aq) $\rightarrow$ Cl^- (aq) NH₄⁺ (aq)

NH₄⁺ + H₂O $\rightleftharpoons$ NH₃ + H₃O⁺ (aq)

3) NH₃ + H₂O $\rightleftharpoons$ NH₄⁺ (aq) + HO^-.
