Derive the ionic product of water and give its value at `25^(@)C`.

Explanation

Consider the Ionisation of water as a weak electroyte.
`H_(2)O_((l))+H_(2)O_((l))hArrH_(3)O_((aq))^(+)+OH_((aq))^(-)K=([H_(3)O^(+)]+[OH^(-)])/([H_(2)O])`
By convention `[H_(2)O]` is taken as constant `K_(w)=[H^(+)][OH^(-)]`
Where `K_(w)=` Ionic product of water and its valule is `1xx10^(-14)`
