Question

pH of a solution in which `["H"^(+)] = 1.25 xx 10^(-12) "M"`?

Answer 1

See the answer below...

Explanation:

I think,you are new about `pH`.

It is formula that, `color(red)(pH=-log_10[H^+]`

Hence the `color(red)(pH` of the solution is `=>color(red)(-log_10(1.25xx10^-12)=11.9)`

Hope it helps....
Thank you...
