Lab: Periodic Trends

by Robert Lucas

This lab covers periodic trends. Instructions: We will be considering three substances today: Potassium, Calcium, and Zinc. We are trying to determine which of these substances is most reactive when combined with water. You will need to decide how you will determine what is most and what is least reactive and take data and observations accordingly.
