10 mL of 
CH 3 COOH solution is mixed with 10 mL of 
NH 4 OH solution. The change in pH of solution upon diluting each solution to double volume will be : (pK a of CH 3 COOH = 4.76, pK b of NH 4 OH = 4.74)
Text Solution
Verified by ExpertsThe correct answer is:
D
pH of a salt solution made from weak acid and weak base = 
(pK w + pK a – pK b )
= independent of concentration of salt solution
