  1. 10.6 pH and Concentration LO: I understand how pH is related to the hydrogen ion concentration.

  2. The pH of a solution depends on the hydrogen ion concentration: [H+] = 0.01 = 10-2 pH = 2 Estimating the pH of a solution: [H+] = 0.00847 mol l-1. Between 0.001 and 0.01 10-3 10-2 pH ~ 2.1 LO: I understand how pH is related to the hydrogen ion concentration.

  3. 10.6.2 Ionic Product for water [H+] = 10-7 mol l-1 = [OH-] Ionic product for water: = [OH-] x [H+] The pH of water is 7. = 10-7 x 10-7 = 10-14 mol2 l-2 2 10-2 10-12 10-14 6 10-6 10-8 10-14 11 10-11 10-3 10-14 LO: I understand what is meant by the ionic product for water.

  4. 10-14 [H+] 10-14 10-9 10.6.3 Calculations involving the Ionic Product Calculate [OH-] of a solution with pH = 9. [OH-] x [H+] = 10-14 mol2 l-2 [OH-] = = = 10-5 mol l-1 LO: I know how to use the ionic product in calculations.

  5. 10-14 [OH-] 10-14 10-2 [OH-] x [H+] = 10-14 mol2 l-2 Calculate the pH of a 0.01M solution of NaOH. [H+] = = = 10-12 mol l-1 pH= 12 LO: I know how to use the ionic product in calculations.
