At a particular temperature, the K_(w) of a neutral solution was equal to 4xx10^(-14) . Calculate the concentration of [H_3O^+] and [OH^-].

Answer»

Solution :Given solution is NEUTRAL
`therefore [H_3 O^+]=[OH^-]`
Let `[H_3 O^+]=x ,` then `[OH^+]=x`
`K_(sp)=[H_3O^+][OH^-]`
`4XX10^-14=x.x`
`x^2=4xx10^(-14)`
`x=sqrt(4xx10^(-14))=2XX10^(-7)`
