The concentration of hydronium (H_(3)O^(+)) ion in water is

Answer»

ZERO
`1 xx 10^(-7)` gm ION /litre
`1 xx 10^(-14)` gm ion/litre
`1 xx 10^(-7)` gm ion/litre

Solution :`H_(3)O^(+) OH^(-) + H_(2)`
`pOH + PH = 14, 7 + 7 = 14, ""[H^(+)][OH] = 10^(-14)`
`10^(-7) xx 10^(-7) , [OH^(-)] = 10^(-7)` gm ion/l.
