A) \[p{{k}_{a}}\]
B) \[p{{k}_{a}}+2\]
C) \[p{{k}_{a}}-\log 2\]
D) \[p{{k}_{a}}+\log 2\]
Correct Answer: D
Solution :
\[pH=p{{K}_{a}}+\log \frac{[salt]}{[acid]}\] When extra 0.1 mole sodium acetate is added \[\text{ }\!\![\!\!\text{ Salt }\!\!]\!\!\text{ }=0.2mol\,d{{m}^{-3}}\] \[[acid]=0.1\text{ }mol\,d{{m}^{-3}}\]
