1.	The pK_(a)ofacetic 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» SOLUTION :First CALCULATE `K_(a) and K_(B)`. Then `K_(h)=K_(w)//(K_(a).K_(b)) and h = SQRT(K_(h))`.
