Question

1. Activators of corrosion.
Procedure.
Put a bit of aluminum into each of two test tubes. Add I
ml of copper sulfate solution into the first test tube and 1 ml of copper
chloride solution into the second. Examine the hydrogen gas evolution
Add 1 or 2 drops of sodium chloride solution to the first test tube. Does
hydrogen gas evolve in both test tubes at equal rate? How does the rate of
gas evolution change when sodium chloride is added? Explain the
experiment. Write equations for the reactions.
