Aim : 

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

Method :

Equipment : 

• Beaker
• Red Cabbage
• Hot water 
• Dropper 
• Test Tubes 
• Different samples for testing   

instructions

1.  Get your equipment ready.
2. Tear the cabbage into small pieces and them into the beaker

3. Add about 100mL of hot water 

4. If it's blue let it sit for 10 minutes

5. Get one bottle each of hydrochloric acid and hydroxide 

6. Get a test tube and put hydrochloric acid or hydroxide on the bottle ( It should be the height of the pinky on it's side )

7. Put 1 to 3 drops of cabbage juice and see what colour turns out.

You can experiment how many colour that you make. Sometimes it can mix it each other colours. You can put a lot of acid but DON'T SPILL IT.

The result there out great. The blue tube has to have a lot of hydrochloric acid and a touch of cabbage juice turn out. The other tube turned to galaxy by accident 

If you spill the acid just put water on it and it will be okay
