1. Silver Nitrate Lab – Day 1 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 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

4. Warm - Up What is a limiting reactant? What is an excess reactant?
Make a prediction:
If you react a 3.2 g copper wire with 0.42 g of AgNO3, what will be the limiting reactant?

5. Objective Today I will be able to:

8. Silver Nitrate Lab Day 1

9. Day 1 Day 1- Today we are setting up the reaction
Day 2 – Filtering the silver and drying the silver
Day 3 – Finding the mass of silver produced and calculations

10. Silver Nitrate Lab Safety
Wear goggles, aprons and closed toe shoes in the lab
Do not spill silver nitrate on your hand. It will stain your hands.
One person from the group will handle the silver nitrate and wear gloves
Label test tube with Copper and Silver Nitrate with a piece of tape. After the reaction has been set up place test tube in the designated test tube rack

11. Silver Nitrate Lab Record the mass of your groups copper wire
Record the mass of silver nitrate used
We are only using 0.4 g of Silver Nitrate
The person handling the silver nitrate must wear gloves
Label the ring stand and the bin you are using with masking tape
Fill out the class data table

12. Limiting Reactant Practice
After completing the lab set up, complete the limiting reactant practice at your desk. We will work on the practice over the next 3 classes.
