One litre of a buffer solution containing 0.01 M NH4Cl and 0.1 M NH4OH having pKb of 5 has pH of
A.9
B.10✓ Correct
C.4
D.6.
Explanation
We know that, ammonium hydroxide and ammonium chloride is a basic buffer. So, to calculate its pH we have- b pOH pK log[salt]/[base] pOH 5 log0.1 pOH 4 and,pH 14 4 10
