The percentage deprotonation of a 0.115 M solution of benzoic acid (a weak, monoprotic acid) is 2.1%. What is the pH of the solution
Answers: 3
= 
( HA ---> H⁺A⁻ )
= 0.021 
= 
![[H^+]=c\times \alpha](/tpl/images/0516/4496/4fc41.png)
![[H^+]=0.115\times 0.021=0.0024](/tpl/images/0516/4496/7e639.png)
![pH=-log[H^+]](/tpl/images/0516/4496/15713.png)
![pH=-log[0.0024]=2.6](/tpl/images/0516/4496/aa86c.png)
