A) 5.8
B) 4.34
C) 5.21
D) 4.76
Correct Answer: D
Solution :
[d] Total volume \[=100\text{ }mL\] \[\left[ acid \right]=10mL\times \frac{1.0}{100}=0.1\] \[\left[ salt \right]=20mL\times \frac{0.5}{100}=0.1\] pH of acidic buffer \[=p{{K}_{a}}+\log \frac{[salt]}{[acid]}\] \[=4.76+log\frac{0.1}{0.1}=4.76\]You need to login to perform this action.
