3 Calculating pOH pOH is the presence of __________________ in solution.
When calculating for pOH, the following formulas will be used: ______________________________

4 Calculating pH using pOH & Vice Versa
When calculating for pH, the following formula will be used: _______________________ If pH=6, then pOH = ___________________. ACID or BASE If pOH=10, then pH = ___________________. ACID or BASE

5 White Board Activity!

6 What is the pH of a solution with a H3O+ concentration of 6.3 x 10-7 M?

7 What is the hydrogen ion concentration of an aqueous HCl solution that has a pH of 3.0?

8 What is the pOH of a 0.0235 M HCl solution?

9 What is the pOH of a solution with a OH- concentration of 2.0 x 10-2 M?

10 What is the OH- concentration of a solution if the pH is 9.2?

11 5. 6 grams of hydroiodic acid are dissolved in 1. 5 L of solution
5.6 grams of hydroiodic acid are dissolved in 1.5 L of solution. Determine the concentration and pH of this solution.

12 Calculate the [H+], [OH-], pH, and pOH for a 0.42 M solution of NaOH.
