Lesson 5
Part B&C
Learning Intention: Determine how to verify the concentration of an unknown/standard solution.
Success Criteria
2. I can explain techniques that minimize errors that could occurring during titration. (e.g. pipetting accurately)
4. I can define the following terms: concentration and mole.
5. I can calculate molecular mass.
6. I can combine titration equations (c = n/V, n = m/M) and stoichiometry to solve for an unknown concentration.
7. I can collect and process accurate data.
Learning Tasks
(Day 1) Complete the pre-learning for this section by completing SciPad pages 8, 9 & 11 to learn about moles, molecular mass, and concentration.
Do Now (Day 2): Test your application of your pre-learning by attempting the Part B (Teaching Version) Question.
Copy down the Part B calculation notes.
(Day 3) Start collecting data for Part C (Teaching Version)
(Day 4) Finish collecting data and give the calculations a go.
Copy down the Part C calculations notes.
(Day 5) Study session to revise the calculations from last term.
(Day 6) Complete Practice Part B (Answers)
(Day 7) Start Practice Part C (Data collection)
(Day 8) Assess Part B
(Day 9) Finish Practice Part C & Feedback
(Day 10) Assess Part C (Data Collection)
(Day 11) Finish Part C

Teacher Notes
Part C Teaching Version used 0.1 M HCl that was labelled as "10-Fold Diluted Purified Household Sour Cream" and 0.1 M NaOH.
Part C Practice Version used 0.2 M HCl that was labelled as "4-Fold Diluted Purified Household Buttermilk" and 0.15 M NaOH.
