#pH=-log_(10)[H_3O^+]#

Explanation:

That's the defining relationship, which must be committed to memory, as well as the relationship for #pOH#:

#pOH=-log_(10)[HO^-]#

In water, #pH+pOH=14# under standard conditions.

See elsewhere for examples of using #pOH# and #pH# in a calculation.

And whatever you do, do not be intimidated by the #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.
