Question

If a salt of strong acid and weak base hydrolysis appreciably (Alpha = 0.1), which of the following formula is to be used to calculate degree of hydrolysis 'alpha'? (a) alpha ={Kw/(Ka. a)} (b) alpha ={Kw/(Kb. a)} (c) alpha ={Kw/(Ka. Kb)} (d) None of these ​

Answer 1

Answer:

Option b

Hydrolysis of a salt containing a strong acid and weak base

Hydrolysis constant is equal to KW by Kb

Find the pH of the solution

pH =1/2(log C + pkw -pkb)

Answer 2

Answer:

D

Explanation:

None of these
