Answer:

10.6.

Explanation:

What is given?

[H⁺] = 2.79 x 10⁻¹¹ M.

Step-by-step solution:

Let's see the formula of pH:

[tex]pH=-\log_{10}[H^+]=-\log_{10}[H_3O^+].[/tex]

Where [H⁺] is the proton concentration in M. So we have to replace the given data in the formula:

[tex]pH=-\log_{10}{}\lbrack2.79\cdot10^{-11}]=10.55\approx10.6.[/tex]

The pH of a [H⁺] = 2.79 x 10⁻¹¹ M solution would be 10.6.
