Question

Calculate the percentage of hydrolysis of ammonium acetate

Answer 1

Answer:

Alpha = sqrt(K/c) where K is the equilibria constant. in general cases

As Ammonium acetate is a weak salt, so we need extra data, namely pKa of , and pH so Hendersen Hasselbach eqn can be used, then from there, alpha is found

pH= pKa + log(a/1–a) where a is alpha

but if we go with normal eqn, then plug in the values, you get

alpha= 5.6%
