Activity Series of Metals
Purpose:� The purpose of this lab is to determine the relative activity of Cu, Zn, Al, Mg, Sn, Pb, Ca, H, and Fe.
- You will be provided with 6M HCl (6 molar hydrochloric acid).� This is a very powerful acid and it is very destructive to human tissue especially your eyes.� GOGGLES MUST BE WORE AT ALL TIMES!!!� BE CAREFUL!
- Use what you have learned from previous labs for greater success on this lab.
- You may request additional materials at your discretion if you have time.
- Label 8 test tubes with one of the 8 metals given (a different metal for each test tube).
- Place a sample of each metal in its designated test tube.
- One test tube at a time, carefully pour 6.0 M HCl into each of the labeled test tubes until each tube is about 1/3 full.
- Carefully observe the rate at which each metal reacts with the acid to determine the relative activity of hydrogen and the 8 metals.
Hint: Don�t be too quick to judge the relative activity of a metal.� (Why not?)
Analysis & Conclusions
- Your conclusion should state the relative activity of hydrogen and the 8 metals indicated above from most active to least active.
- You do not have to write a formal lab report for this.� Just show the order of metallic activity for the eight elements shown above (most active to least active) and write a balanced, net ionic equation for each metal that produced a reaction with the hydrochloric acid.� If more than one reaction is possible for a given metal, show both reactions.
