Concept: Phenolphthalein is an indicator, which detects whether a substance is an acid or a base.
Materials Needed:
200 mL beaker of water
10 - 12 drops of phenolphthalein
3 mL of lime water (saturated calcium hydroxide solution)
straw
Procedure:
1. Fill the beaker with 200 mL of water.
2. Put 10 - 12 drops of phenolphthalein solution in the water.
3. Put 3 mL of lime water into the water (you may have to experiment a bit with the amount so that you do not have to blow forever to get it to change colors.
4. Stir the pink/purple solution.
5. Insert the straw into the beaker and blow OUTWARD.
