This Lab will be our first formal lab. I am giving out a data worksheet to keep you organized in your data collection but it will not be handed in. You will write a data section and calculation section in your formal lab write-up that will be in a google doc that will be shared to you in next couple of days.
Cu (s) + I2 (g) —> Cu? I?
Objectives: 1. To determine the empirical formula of the salt (product).
2. To determine the percent yield of the salt.
The lab will be written up in a shared google doc according the following rubric:
Lab 7 : Synthesis of Copper Iodide
Lab 7 review – This might help with your calculations!
