W.T. Schrenk Society Meeting 2/2/17

  1. Elections

  1. John Theriac was elected Secretary

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