4. Test tube 1 is the control and all others will be compared to it.
5. Add the 2 drops of potassium permanganate and start timing. Record the time that the pinkpurple colour disappears.
6. Repeat the process for each of the other test tubes.
7. Place a few crystals of calcium carbonate in a beaker and an equal amount of calcium
carbonate powder in another beaker.
8. Add about 25 ml of 3M HCl to each beaker. Compare the reactions.
9. Clean up your workstation.
