  1. NEXT YEAR DON'T DO LOG CHARTS AT ALL. DO SIMPLE ESTIMATES OF LOGS USING EXPONENT OF 10

  2. RESPONDERS TODAY 5/7/2012 Standards: 5 Objectives: ●  CST Quiz w responders 41-50 ●  Be able to calculate pH and pOH and be able to convert pH <---> pOH DO NOW: 1. If [H+] = 1 x 10-5 what is the pH? 2. If pH = 5 what is the pOH 3. If the [H+] = 4 x 10-8 what is the pH? HOMEWORK: 1. Ch 19.4 PP’s p. 612 20 (a-c) and p. 631-632 87-89 (4 pts) 2. PRINT Tutorial on Neutralization reactions using M1V1a = M2V2b 3. CST 41-50 - work problems on printed paper, non-calc needs ans w reason & page #, calc, needs given, find and calcs. (chk on-line vid) ========================================================== STAMPS:   ●  Journal 5/4 1. Ch 19.3 PP's p. 609   18 (a-c) and 19 (a-c) (5 pts) Std 5 Watch the 2 videos on how to use the pH chart

  3. CST Review - lunch every day for the next 10 school days. If you attend you get 3 pts ex cr for each day

  4. Intro to Chart for finding pH from concentration http://www.youtube.com/watch?v=IQnzryo6Bwo 3 Examples Video http://www.youtube.com/watch?v=2x5QeFBZvFU

  5. pH = -log [H+] pOH = -log [OH- ] pH + pOH = 14 Kw = [H+][OH1- ] = 10-14

  6. Find the pH of a solution of HCl with a 3.7 M 1 Answer example: 2.2x10-2

  7. 2 Find the pOH of a solution of HCl with a 3.7 M

  8. 3 Find the pOH of a solution of NaOH with a 8.7 M Answer example: 2.2x10-2

  9. 5/8/2012 Standards: 5 (Acids & Bases) Objectives: ●  Be able to perform pH & pOH calcs ●  Be able to do dilutions with M1V1a = M2V2b DO NOW: 1. [ H+ ] = 6.6 x 10-6 calculate the pH 2. [ OH- ] = 1.7 x 10-3 calculate the pOH 3. pH = 5.19, calculate [ H+ ] HOMEWORK: 1. p. 614 21 (a-c), 22 (a-d) and p. 621 30-32 (5 pts) 2. CST 51-60 Same directions (5 pts) ======================================================= STAMPS: ●  Journal 5/7/12 1. Ch 19.4 PP’s p. 612 20 (a-c) and p. 631-632 87-89 (4 pts) Std 5 2. PRINT Tutorial on Neutralization reactions using M1V1a = M2V2b (1 pts) Std 5 3. CST 41-50 - Same directions. (5 pts) Std 5 RESPONDERS TODAY
