Answer

4.0 x 10 ^ -10 pH = 12.26 [OH-] = 2.0 x 10 ^ -5 pH = 5.86

Work Step by Step

Let's convert pH to pOH first because it is asking the hydroxide ion concentration. Remember pH+ pOH=14. Recall the sum of pH and pOH is 14. We can find the pH of the solution by subtracting the pOH from 14. Let's convert pH to pOH first because it is asking the hydroxide ion concentration. Remember pH+ pOH=14.
