Jen Ciampi & Julia Nan Block 4 November 2008 Lab: Stoichiometry…Can You Make 2.00g of a Compound? Objective: Use your skills of predicting chemical reactions, balancing equations, and calculating molar mass to solve a complex stoichiometry problem. Then test your laboratory techniques by mixing the reactants and isolating exactly 2.00g of a compound. Materials: 25 or 50mL beakers 100mL beakers Funnel Glass stirring rod (2) 25mL graduated cylinder Water Balance scoopula Ring stand w/ clamps Procedure: 1. Predict the product of the reaction between aqueous Zinc Sulfate and aqueous Calcium Acetate. 2. Balance the equation and set up a stoichiometry problem to find the amounts needed to get 2.00g precipitate. 3. record the amount of reactants needed 4. Once you have calculated the amounts of each reactant that you need (2.4g Zinc Sulfate and 2.3g Calcium Acetate), put an empty beaker on the balance and clear out the weight by pressing the “on” bottom. Once the balance shows 0.0 g the screen with the beaker, measure out the correct amount of Zinc Sulfate in the beaker.
