Part 3. reactions of metals with other metal ions 

  • Place a clean 1 inch-square of metal foil (sheet) of each of these metals Cu, Zn and Pb on a flat surface.
  • Clean the metal surfaces by sanding them with fine sandpaper or steel wool.
  • Place one or two drops in spots of each of these solutions in a clockwise order on the metal surfaces:
A. 0.5 M Ag + size 12{"Ag" rSup { size 8{+{}} } } {}
B. 0.5 M Cu 2 + size 12{"Cu" rSup { size 8{2+{}} } } {}
C. 0.5 M Zn 2 + size 12{"Zn" rSup { size 8{2+{}} } } {}
D. 0.5 M Pb 2 + size 12{"Pb" rSup { size 8{2+{}} } } {}
  •  NOTE: Do not test a cation of a metal on a square of the same metal such as Cu 2 + size 12{"Cu" rSup { size 8{2+{}} } } {} ion and Cu metal.
  • Watch for color changes in each spot as evidence of reaction. If you are not sure whether the reaction has occurred, rinse the plate with water. A distinct spot of a different color on the surface is good evidence for the reaction.
  • Write net ionic equations for each reaction . Arrange Ag, Cu, Pb and Zn in order of their increasing strength as reducing agents. If a metal A reacts with a cation of another metal B, metal A is a stronger reducing agent, more reactive than metal B.
  • Rinse and dry each square of metal and return it to the correct beaker on the reagent shelf for other students to use.

Part 4. flame tests

One station set up that all sections will rotate through

Clean a spatula wire by dipping it into dilute hydrochloric acid (3M) and then holding it in a hot Bunsen flame. Repeat this until the spatula doesn't produce any color in the flame.

When the spatula is clean, moisten it again with some of the acid and then dip it into a small amount of the solid you are testing so that some sticks to the spatula. Place the spatula back in the flame again.

If the flame color is weak, it is often worthwhile to dip the spatula back in the acid again and put it back into the flame as if you were cleaning it. You often get a very short but intense flash of color by doing that.


  • Chloride salts of Li, Na, K, Rb, Cs, Ca, Ba, Cu, Pb, Fe (II) and Fe(III) Sr (nitrate salt).
  • Glass rods with loops of Pt wire.
  • Bunsen burner/clicker.
  • Concentrated nitric acid or hydrochloric acid.

Record your observations on your report form.

It should be noted that sodium is present as an impurity in many if not most metal salts. Because sodium imparts an especially intense color to a flame, flashes of the sodium may be observed in nearly all solutions tested.
