Silver Nitrate Lab – Day 2 Limiting Reactants

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

Silver Nitrate Lab Day 2

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

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

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.

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