Q. Addition of sodium acetate to 0.1 M acetic acid will cause
A) Increase in pH
B) Decrease in pH
C) No change in pH
D) Change in pH that cannot be predicted
Explanation
(a)
Addition of sodium acetate in acetic acid solution, due to common ion $NH_{4}^{+}$ the ionisation of acetic acid is supressed so concentration of $\lbrack H^{+}\rbrack$ decreases. Hence, pH of solution increases.
