Approximate relationship between dissociation constant of water (K) and ionic product of water `(K_(w))` is

Options

A. `K_(w) = K `
B. `K_(w) = 55.6 xx K `
C. `K_(w) = 18 xx K `
D. `K_(w) = 14 xx K `

Answer

B

Explanation

Dissociation constant
`H_(2)O hArr H^(+) +OH^(-)`
`K = ([H^(+)][OH^(-)])/([H_(2)O]) = (10^(-14))/(55.6)`
`K_(w) = 1 xx 10^(-14)`
So , `K_(w) = 55.6 xx K `
