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

A

Zero

B

`1 xx 10^(7)` g ion/litre

C

` 1xx 10^(-14)` g ion/litre

D

` 1 xx 10^(-7)` g ion/litre

Text Solution

Verified by Experts

The correct Answer is:
D
`H_(3)O^(+) hArr OH^(-) +H_(2)`
`pOH +pH = 14 , 7+ 7 = 14 , " " [H^(+)] [OH^(-)] = 10^(-14)`
`10^(-7) x 10^(-7) , [OH^(-)] = 10^(-7)` g ion/L .
