Red Cabbage Indicator experiment

Materials

1. Red Cabbage

2. Beaker

3. Bunsen Burner

4. Pipette

5. Sodium Hydroxide

6. Hydrochloric acid

7. Test Tubes ( x5)

8. Paper towel

9. Test tube rack

10. Water

Steps

1. Chop up the red cabbage into small pieces. Place in a beaker and cover with a small amount of water.

2. Bring the solution to the boil using a bunsen burner and then turn off the heat. Let it sit to cool down.

3. Pour the cabbage water through a paper towel into a beaker. The dark purple liquid in the jar is the pH indicator liquid.

4. Suck up the indicator into a pipette.

5. In a test tube, use the cabbage indicator and the pH chart below to test the acidity of the the hydrochloric acid and ammonium hydroxide.

Findings.

What is the pH of liquids.

1. Sodium Hydroxide - 11-12

2. Hydrochloric acid - 2-3
