Silver Nitrate Lab, Day 2 Limiting Reactant Practice Chemistry GT 3/16/15

Chem Joke of the Day What did the bartender say to the neutron when it tried to pay for its drink? “For you, no charge!” Drill Lithium metal replaces zinc in a zinc chloride solution. 3.0 g Li and 4.5 g ZnCl2 are present as reactants. How much zinc is produced? Which is the limiting reactant? HW: Study for Moles & Stoichiometry Quiz 3/18 Work on the Mole Project

Objective IWBAT: NOTE: 3/18 – Moles and Stoichiometry QUIZ 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 NOTE: 3/18 – Moles and Stoichiometry QUIZ

Day 2 Day 1—Friday, we set up the reaction Day 2 – Today, we will filter and dry the silver Day 3 – Tuesday, is for measuring 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 Ms. Bloedorn’s demo on filtration technique then filter your sample

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