A) 1 : 10
B) 10 : 1
C) 100 : 1
D) 1 : 100
Correct Answer: B
Solution :
[b] \[pH=p{{K}_{a}}+\log \frac{\text{Salt}}{\text{Acid}}\] \[6=-\log {{10}^{-5}}+\log \frac{\text{Salt}}{\text{Acid}}=5+\log \frac{\text{Salt}}{\text{Acid}}\] \[\log \frac{\text{Salt}}{\text{Acid}}\] must be 1. \[\therefore \]\[\frac{\text{Salt}}{\text{Acid}}\text{=}\frac{10}{1}\] or \[10:1.\]You need to login to perform this action.
