The `pH` of a solution increased from `3` to `6`. Its `[H^(o+)]` will be

Options

A. Reduced by `1000` times
B. Increased to `1000` times
C. Doubled
D. Reduced to half

Answer

A

Explanation

`pH = 3, [H^(o+)] = 10^(-3)`
`pH = 6, [H^(o+)] = 10^(-6)`
`[H^(o+)]` decreases, which is only possible if the solution is diluted to `1000` times, i.e.,
