November 3‚ 2014 Chemistry 1411- 106 Pre Lab Experiment #8 Objective: This Lab will help us to understand oxidation reduction and double displacement through finding the percent composition of pennies. We will also once again be working with titration in this lab. We will titrate the solution until we are only left with a solid form which will tell us about the composition of pennies. Introduction: The weight of a post 1982 penny is 2.5 grams‚ and the percent of zinc is 97.5% leaving only 2.5% copper
