Please help with this question! Given a solution with a pH of 2, determine the pOH of the solution. Type in a numerical answer.

Answer 1

Some things you need to know when dealing with this type of problem:

a). pH = -log [H+]

b). pOH = -log [OH-]

c). pH + pOH = 14

In this problem, we can use (c) above, ie pH + pOH = 14

2 + pOH = 14

pOH = 14 - 2

pOH = 12
