The `pK_(a) ` of acetic acid and `pK_(b)` of ammonium hydroxide are 4.76 and 4.75 respectively. Calculate the hydrolysis constant of ammonium acetate at 298K and also the degree of hydrolysis and pH of (a) 0.01 M and (b) 0.04 M solutions. |

Answer» Correct Answer - `K_(h)=3.25xx10^(-5), h=5.7 xx 10^(-3) and pH = 7. 005` (same in both cases) First calculate `K_(a) and K_(b)`. Then `K_(h)=K_(w)//(K_(a).K_(b)) and h = sqrt(K_(h))`. |
