The degree of dissociation of water at 25^(@)C is 1.9 xx 10^(-7)% and density of 1.0 gm^(-3). The ionic constant for water is

Answer»

`1.0 xx 10^(-14)`
`2.0 xx 10^(-16)`
`1.0 xx 10^(-16)`
`1.0 xx 10^(-8)`

Solution :For water `K_(w) = ([H^(+)][OH^(-)])/([H_(2)O]), K = 1.9 xx 10^(-9), C = (100)/(18)`
`K = 1.9 xx 10^(-9) xx 1.9 xx10^(-9) xx 1000/18`
`= 2.0 xx 10^(-16)`
