Equipment

• Boiling water
• dropper
• test tubes
• different samples for testing

Instructions:

1. Get your equipment ready
2. Ripped the cabbage into tiny pieces into your beaker.
3. Add about 100mL of boiling water. Into your beaker until it takes the colour out.
4. then wait until the colour of the beaker turns purple.
5. then you get your hydrochloric acid and hydroxide
6. then your pour 2cm of hydrochloric acid and add hydroxide into your test tube then you add the red cabbage water.
7. and see what the colour is.

The result was that the more hydroxide you added the pink/red it would get. The more hydrochloric acid you add the purple/ dark colour it would be.
