Define ionic product of water . Give its value at room temperature .

Answer»

Solution :(i) The PRODUCT of CONCENTRATION of `H^(+)` and `OH^(-)`ions in water at a particular temperature is known as ionic product .
(II) The ionic product of water at room temperature `(25^(@) C)` is
`K_(w) = [H^(+)] [OH^(-)]` (or)
`K_(w) = [H_(3) O^(+)] [OH^(-)]`
`K_(w) = (1 xx 10^(-7)) ( 1 xx 10^(-7))`
`K_(w) = 1 xx 10^(-14) mol^(2) DM^(-6)`
