If hydrogen ion concentration in a solut...

If hydrogen ion concentration in a solution is `1xx10^(-5)` moles/litre, calculate the concentration of OH ion in this solution `(K_(w)=10^(-14)"moles"^(2)L^(-2)).`

Text Solution

Verified by Experts

`K_(w)=[H^(+)][OH^(-)]=10^(-14)`
`[OH^(-)]=(10^(-14))/(10^(-5))=10^(-9)mol L^(-1)`
