Acids

 Aim to make red cabbage PH indicator for use on different house hold chemicals 

Red cabbage indicator experiment  

materials 

1 red cabbage 

2 beaker 

3 bunser burner 

4 pipette 

5 Sodium Hydroxide

6 Hydrochloric acid

7 Test Tubes

8 Paper towel

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. Use the cabbage indicator to test the acidity of the different household liquids by slowly putting a drop at a time into the test tube.
