W.T. Schrenk Society Meeting 2/2/17
Elections
- John Theriac was elected Secretary
- Lily Nguyen was elected Schrenk Representative
- Lab
- Zinc coating copper pennies
- https://www.sciencecompany.com/Turn-Copper-Pennies-Into-Silver-and-Gold-Pennies.aspx
- Some notes to consider for if done again are as follows:
- The pennies need to be flipped after about 4 minutes to get both sides
- To keep things from touching we need more beakers with 1 penny per beaker if small
- Turn the hot plates up to at least 300 to speed up boiling
- Halve the recipe
- Put some ZnSO4 into other beakers, so more than one person can weigh out it at once
