# How do you calculate the pH of a saturated solution?

You know (or should know) the definition of a saturated solution (it's defined here in many places), and you know that $p H$ $=$ $- {\log}_{10} \left[{H}_{3} {O}^{+}\right]$. So first you need $\left[{H}_{3} {O}^{+}\right]$ of the solution.
If it were a saturated solution of $N a C l$, which possesses no acid base behaviour in water, can you quote $p H$?
