Reaction of aluminum metal with copper (II) chloride solution

Copper (II) ions will hydrolyze to produce an excess of hydrogen ions, making the copper (II) chloride solution slightly acidic. Aluminum metal is always covered in a thin, but protective layer of aluminum oxide, Al 2 O 3. The chloride ion helps to separate the aluminum from the oxygen so that the aluminum can react with the copper

A Silver/Copper Replacement Reaction

Lab Hints. Some brands of copper wire are lacquered and will not react adequately until the coating has been removed with steel wool. Test your wire before allowing students to begin. In many areas, there are sufficient chloride ions in tap water to react with the silver ion to produce a cloudy precipitate. Use distilled or deionized water.
