1. Silver Nitrate Lab – Day 2 Limiting Reactants

2. Evaluation/Assessment:
Objective:
Today I will be able to:
Calculate the mass of silver produced when reacting copper with silver nitrate
Apply filtering techniques to separate a solution
Apply stoichiometric ratios to finding the mass of reactants and products
Determine the limiting and excess reactants in a chemical reaction
Evaluation/Assessment:
Informal Assessment – Monitoring student interactions as they complete the practice and the lab
Formal Assessment – Analyzing student responses to the lab and the limiting reactant practice
Common Core Connection
Make sense of problem and persevere in solving them
Look for and express regularity in repeated reasoning
Attend to precision
Use appropriate tools strategically

8. Silver Nitrate Lab Day 2

9. Day 2 Day 2 – Today we are filtering the silver and drying the silver
Day 3 – Tomorrow we are finding the mass of silver produced and calculations

10. Silver Nitrate Lab Safety
Wear goggles, aprons and closed toe shoes in the lab
Use distilled water only
Be careful when pouring distilled water into the funnel to avoid overflowing
Watch Mr. Klotz’s demo on filtration technique then filter your sample

11. Limiting Reactant Practice
After completing the filtration, complete the limiting reactant practice at your desk. We will work on the practice over the next 3 classes.

12. Exit Ticket
What are some possible sources of error that could have occurred during the copper silver nitrate lab?
