At certain temperature, the H^(+) ion concentration of water is 4 xx 1

1.	At certain temperature, the H^(+) ion concentration of water is 4 xx 10^(-7) 'M then the value of K_(w), at the same temperature is
Answer» `10 ^(-14) M^(2) ` ` 4xx10 ^(-14) M^(2) ` ` 1.6 xx 10 ^(-13) M^(2) ` ` 4xx10 ^(-7) M^(2) ` SOLUTION :` [H^(+) ] [OH^(-)]= K_W , As [H^(+) ] =[OH^(-)] ` ` (4xx10 ^(-17))(4XX 10^(-17)) = K_W` ` 16 xx 10 ^(-14)M^(2)(or) 1.6 xx 10^(-13)M^(2) `
