- Go over Lab 20B quiz.
- Go over acid #2 worksheet
- I will be able to find the pH and pOH of a weak acid or weak base. See Ka and Kb
- Do: Acid #1 WS
- Video: The Strengths and Weakness of Acids and Based (Ted Ed)
2. Lab 20B Quiz
3. Any Q’s from the WS on pH, pOH and Kw?
4. Practice Quiz on pH, pOH, and Kw: pH Practice Quiz
3. Video: pH and pOH
- Video Review:
2. Lab 20B Discussion – ask questions! Be able to analyze data, write equations, and rank the acids from strongest to weakest.
3. Lab 20B Quiz next class.
4. I will be able to apply Kw to calculate the pH and pOH of a solution. See block 8 notes here: Equilibrium of Water
5. Do: Worksheet pH-pOH Worksheet. See answer key here: pH Intro Basic Math answer key
- Go over #5-10 on the worksheet.
- Do: Lab 20B a) identify the color of the acid form of the indicator and the base form of the indicator, b) make observations of the reactions between the HAs and the HIns, c) analysis – which acid is stronger – the HA or HIn? Be able to explain why. d) Rank the acids from the strongest to the weakest acid
- Next class: Be prepared to discuss your results and to JUSTIFY why/how you ranked your acids.
- Review: Arrhenius and Bronsted-Lowry Acids and Bases. Go over Self-Test Worksheet #1-4. See block 7 answers here: Self Test Worksheet Day 1
- I will be able to compare the strengths of acids and bases and determine whether reactants or products are favored.
- Do: Self-Test # 5-10
- Do: Prelab for Lab 20B –make a larger data table for next class. See sample table here (but make it much bigger!) Lab 20B Ranking the Strengths of Acids

copy of the AP Chemistry Periodic Table and Equation Sheets here:
- New seating plan!
- Activity: classify the chemicals A-F and the common household products based on their similarities.
- I will be able to identify Arrhenius and Bronsted-Lowry acids and bases.
- Read section 16.1-16.3 and use the questions to help focus your reading. Intro to Acids and Bases
Today, students from block 7 (and some from block 8) enjoyed a presentation by UBC Chemistry professor Dr. Mark MacLachlan. Here is an interview he made with Global News about other research he is involved with:
For those of you who like to learn by osmosis, here is one of my favorite children’s books that deals with a similar topic:
And this is another good book he wrote–quite funny!
- Fill in the Work Habits Self-Reflection and Goal Setting for Term 2.
- Go over the Keq test and do test corrections.
- Intro to ch16 . See ch16 Learning Log (ch16 Acid-Base Equilibria Learning Outcomes ) and as you are reading and taking notes, be able to answer these questions: Intro to Acids and Bases
Reminder: Wed. Nov 28 – we will be attending a presentation/workshop with Dr. Mark MacLachlan, UBC Chemistry during Block 7. Block 8 students who have returned their field trip forms should also attend.
As a bonus, this counts as one of the presentations you can attend for your CLC!! Pick up a form from me at the end of the presentation and fill out the reflection questions.
- Hand in ch15 notes and review worksheet.
- Today, students wrote the Keq test.
This concludes the assessments for Term 1 for AP Chem12.
- Fizz Quiz – 2008 AP Chem exam Form B Question #1. (Q2 is good practice if you are doing the retest for ch14 tomorrow)
- Finish ch15 Notes and WS. Mark the WS (answer key is posted on last day’s blog) and do your corrections. Hand in both next class.
- Keq Test on Wednesday – about 6 Questions, all calculations. Show your work!
- Goal Day tomorrow – deadline for assessments for Term 1.
