A) \[pH=4.70\]
B) pH < 4.70
C) pH of solution will be equal to pH of acetic acid
D) 4.76 < pH < 5.0
Correct Answer: D
Solution :
[d] \[pH=p{{K}_{a}}+log\frac{[salt]}{[acid]}\] \[=4.76+log\frac{\frac{7.5}{100}}{\frac{5}{500}}=4.7+log1.5=4.87\] Hence correct answer is \[4.76<pH<5.0\]You need to login to perform this action.
