Question

What is the ph of an aqueous solution with [h3o+] = 2×10−14 m ?

Answer 1

The general formula for finding pH is:


`pH=-log[ H _(3)O ^(+)]` -> This equation could also work with H+.

So using the formula and plugging in the hydronium ion concentration:


`pH=-log(2* 10^(-14)M)`


`pH=13.7`

So the solution has a pH of 13.7.
