Answer:

#pOH=10#.....................what is solution #pH#?

Explanation:

#pH+pOH=14# in aqueous solution under standard conditions. This is something you will simply have to remember.

And so #pOH=14-pH=14-4#, because #pH=-log_(10)[H_3O^+]#

See here for background. The use of logarithmic scales derives from pre-calculator days, when chemists, physicists, and ACCOUNTANTS used log tables to calculate the products of very large or very small numbers.
