![ka= \frac{[H^+][CH3CH2COO^-]}{[CH3CH2COOH]}](/tpl/images/0327/3477/57edb.png)
![[CH3CH2COO^-] ](/tpl/images/0327/3477/557ff.png)
= 0.05![[CH3CH2COOH]](/tpl/images/0327/3477/fb4be.png)
= 0.10![\frac{[H^+][0.05]}{[0.1]}](/tpl/images/0327/3477/ada55.png)
![[H^+] = \frac{(1.259*10^-5)(0.1)}{0.05}](/tpl/images/0327/3477/96b2b.png)
![[H^+]= 2.513*10^-5](/tpl/images/0327/3477/8bdb7.png)
] = -log(2.513*10^-5)= 4.59.Another question on Chemistry
