At certain temperature the proton concentration of pure water is `2.5 xx 10^(-7) M`. What is the hydroxyl ion concentration ? What is the magnitude of `K_w` ?

Text Solution

Verified by Experts

For pure water, `[H^+] = [OH^(-)]`
Concentration of `[OH^(-) ] = 2.5 xx 10^(-7) M`
Ionic product of water `= K_w = [H^+ ][OH^(-)] = (2.5xx10^(-7) M)^2 = 6.25 xx 10^(-14) mol^2 L^(-2)`
