1. Experiment 15 Activity Series
CHE116

2. Purpose of This Experiment
Gain more experience with chemical reactions
Gain experience with the relative reactivity of metals
Work in groups of 2
CHE116

3. Remember…. Use only ¼ inch size pieces of Mg metal and Cu metal
The following will not be used in exp. 15:
Ca metal and Fe2+ solution
CHE116

4. Part A
The relative activity of each metal is based on the metal’s reaction with HCl(aq)
Some reactions are very slow
For calcium: Reaction with HCl = Yes
Observation: Ca dissolves and H2 gas forms
Equations: Molecular and net ionic formats
CHE116

5. Part B
The relative activity of each metal is based on the metal’s reaction with a solution of a metal ion (other than itself)
There is no Calcium metal: observations for Ca(s) row of table are Yes, reaction occurs with each metal ion solution
There is no Fe2+ solution: observations for the Fe2+ column are Ca = yes, Cu = NR, Fe = NR, Mg = Yes, slowly, Sn = NR, Zn = almost No

6. Clean-up
Please dispose of all solutions in the appropriate waste container.
