Step 1 - The definition of pH

The pH of a solution is defined as:

$pH=-log[H^+\rbrack$

Therefore, if we know its H+ concentration, we can calculate its pH.

Step 2 - Calculating the pH

$\begin{gathered} [H^+\rbrack=10^(-12)mol/L \\ \\ pH=-log10^(-12) \\ \\ pH=-(-12)* log10=12 \end{gathered}$

Answer: the pH of this solution is 12.
