value of water at 50.0° C is 
.![pH=-\log[H^+]](/tpl/images/0122/1688/cf945.png)
![6.630=-\log[H^+]](/tpl/images/0122/1688/7300b.png)
![[H^+]=2.344\times 10^{-7}M](/tpl/images/0122/1688/5d847.png)
![[OH^-]=[H^+]=2.344\times 10^{-7}M](/tpl/images/0122/1688/7a187.png)
![K_w=[H^+][OH^-]](/tpl/images/0122/1688/bc68a.png)
![K_w=[2.344\times 10^{-7}M][2.344\times 10^{-7}M]=5.49\times 10^{-14}\approx 5.50\times 10^{-14}](/tpl/images/0122/1688/1b592.png)
