Red cabbage indicator

 Aim:

I want to find out how to tell if something is an acid

Method:

Equipment:

• Beaker
• Red cabbage
• Boiling water
• Dropper
• test tubes
• Different samples for testing

Instructions:

1. Get equipment
2. ripped the cabbage into small pieces and added to the beaker
3. add about 100 mL of hot water
4. Wait for the reaction
5. Add Hydrochloric acid into a test tube
6. Add some cabbage water to the test tube.
7. in another tube add Hydroxide 
8. in the same tube add The Cabbage water

Results: 

In this test tube, I added both of the acids to make a different color (and the cabbage water) 

In this one, I only used Hydrochloric acid to make red (and the cabbage water)

In this test tube, I added only Hydroxide acid and the cabbage water
