1. Understand the Relationship
* pH and pOH: pH and pOH are related to each other through the following equation:
pH + pOH = 14
* Hydroxide (OH-) and pOH: pOH is the negative logarithm (base 10) of the hydroxide ion concentration:
pOH = -log[OH-]
2. Calculate the pOH
* You're given [OH-] = 1.0 x 10^-12 M
* pOH = -log(1.0 x 10^-12) = 12
3. Calculate the pH
* pH + pOH = 14
* pH = 14 - pOH = 14 - 12 = 2
Therefore, the pH of the solution is 2.
