$p H = - {log}_{10} [H_{3} O^{+}]$ $pH=-log_(10)[H_3O^+]$

Explanation:

That's the defining relationship, which must be committed to memory, as well as the relationship for $p O H$ $pOH$ :

$p O H = - {log}_{10} [H O^{-}]$ $pOH=-log_(10)[HO^-]$

In water, $p H + p O H = 14$ $pH+pOH=14$ under standard conditions.

See elsewhere for examples of using $p O H$ $pOH$ and $p H$ $pH$ in a calculation.

And whatever you do, do not be intimidated by the $log$ $log$ function. It was introduced to make complex calculations easier, and it does. If you have problems, voice them here, and someone will help you.
