The `P^(H )`of a solution is 6. Its `[H_(3),O^(4)]` is decreased by 1000 times. Its `P^(H)` will be

A

`9`

B

` 6.96`

C

` 7.04`

D

` 8`

Text Solution

Verified by Experts

The correct Answer is:
A
` pH = 6, [H^(+) ] = 10 ^(-6) ," conc. of " H^(+) ` decreased by 1000 times means `[H^(+) ] ` becomes `10 ^(-9) ` new pH= 9
