A solution has pH = 5, it is diluted 100 times, then it will become

Answer»

Neutral
Basic
Unaffected
More acidic

Solution :pH = 5, MEANS `[H^(+)] = 10^(-5)M`
After DILUTION `[H^(+)] = 10^(-5)//100 = 10^(-7)M`
`[H^(+)]` from `H_(2)O` cannot be neglected.
Total `[H^(+)] = 10^(-7) + 10^(-7) = 2 XX 10^(-7)`
`pH = 7 - 0.3010 = 6.6990 = 7` (neutral).
