The ionic product of water at `80^(@)C` is `2.44xx10^(-13)`. What are the concentrations of hydronium ion and the hydroxide in pure water at `80^(@)C`?

Explanation

`K_(W)=[H^(+)][OH^(-)]`
`K_(w)=2.44xx10^(-13)`
For pure water `[H^(+)]=[OH^(-)]`
`:. [H^(+)]=K_(w)`
`[H^(+)]= sqrt(2.44xx10^(-13))`
`=4.94xx10^(-7)` moles/lit
`:. [OH^(-)]=4.94xx10^(-7)` moles/lit
