2. Friday, March 12 th : “A” Day Monday, March 15 th : “B” Day Agenda  Homework/Questions/Problems/Collect  Quiz over section 13.2  Movie: “Chemistry Module 4: Solutions and Dilutions”  Homework: – Dilutions worksheet Looking Ahead: We will be in the lab next class period…

3. Homework Questions/Problems?

4. Section 13.2 Quiz  Use your book, your guided notes, and your lab partner to complete the quiz…

5. Movie: “Chemistry Module 4: Solutions and Dilutions”  You DO NOT have to take notes, but YOU WILL be using the dilution equation, M 1 V 1 = M 2 V 2 in your homework and in the lab next week…

6. Solution Dilution M = mol L M x L = mol OR Solution Dilution M 1 V 1 =M 2 V 2

7. Dilution Example #1 How many Liters of 0.155 M Ni(NO 3 ) 2 can be made from 75.0 mL of 12.0 M Ni(NO 3 ) 2 ?

8. Dilution Example #2 What volume of 19 M NaOH must be used to prepare 1.0 L of a 0.15 M NaOH solution ?

9. Homework  Use the solution dilution equation, M 1 V 1 = M 2 V 2 to complete the homework worksheet…  We will do a lab write-up and conduct a solution dilution lab next time…
