![K_w=[H^+]\times [OH^-]](/tpl/images/1031/9890/a4a9d.png)
![7.7\times 10^{-14}=[H^+]\times [OH^-]](/tpl/images/1031/9890/7be88.png)
![[H^+]=[OH^-]](/tpl/images/1031/9890/0669d.png)
![2[OH^-]=7.7\times 10^{-14}](/tpl/images/1031/9890/76673.png)
![[OH^-]=3.85\times 10^{-7}](/tpl/images/1031/9890/561a3.png)
