- Warm up! How would you separate the ions individually in a solution that contains Mg2+, Pb2+, and Zn2+?
- I will be able to explain and calculate the solubility of solutions.
- Study guide notes: Solubility study guide day 2
- Hand in Lab 20G.
- Intro to Solubility – Review Solutions, Solubility, Precipitations and the Solubility Table
- Fill in the Study Guide. See copy of study guide here: Solubility Study Guide
- Do: Worksheet on Solutions – you should be able to answer #1-24. See copy of worksheet here: Ch12Unit3Review-1 and answer key: Ch12Unit3ReviewKEY (1)
- Other handouts: Ch12Unit3Review (1) ch17 Additional Aspects of Aqueous Equilibria Learning Outcomes
- Do: Lab 20G Parts 3 and 4. If you didn’t finish all of the titrations, you will be given some time next class to finish them. Do the calculations for the parts you have completed:
Part 1 – Calculate the molarity of the oxalic acid dihyrate you made (this is your primary standard).
Part 2 – Calculate the molarity of the NaOH solution (you are standardizing it)
Part 3 – Find the molar mass of the unknown monoprotic acid. Make sure to include which LETTER unknown you used.
Part 4 – Find the Ka of the unknonw monoprotic acid. Make sure to include which LETTER unknown you used. Show your work using a RICE table!
- In the meantime, make sure you have read the first half of ch17 and have taken notes.
- Go over the science fair rubric.
- Do: Lab 20G Parts 1 and 2.
- For part 1, find the molarity of oxalic acid dihyrate that you made.
- For part 2, calculate the molarity of the NaOH solution.
- Go over science experiment scenarios in preparation of judging science fair projects.
- Demo: how to do a titration
- Block 8 – Lab 20G Part 1
- Block 7 – will do Lab 20G Parts 1 and 2 on Friday. Be efficient!
- Demo: Buffers – how they prevent drastic changes in pH.
- Do: Prelab for Lab 20G.
- Reminder: Goal Day on Wed. 12:30pm is the start of retest (written section) for the acids and bases test.
- Reminder: Ch16 Ka,Kb,and Salts test on Friday.
- Go over Lab 20D Salt Hydrolysis lab – any Q’s.
- I will be able to identify Lewis acids and bases.
- Finish reading chapter 16 and making notes.
- Do: Ch16 Review WS. See answer key here: Ch16 Review Worksheet
- Answers to the WS from last class on Salt Hydrolysis (in the stapled booklet): Hydrolysis of Salts Worksheet and Answers
- Warm Up! What is the pH of a 0.500M solution of Na2CO3?
- Finish Lab 20D and confirm whether your predictions were correct or not.
- Do: Worksheets (1. Salt Hydrolysis and Lewis acids and bases, 2. ch16 review worksheet)
- Note: Chapter 16 test on Friday, Jan 25.
