Aim: To make acid-base indicators using everyday substances.
Equipment:
- Red cabbage
- Tea
- Beetroot
- Turmeric
- Cranberry juice
- A beaker
- Water
Method:
Task One:
- You now have five beakers, each containing a different indicator.
- Using a pipette, place 5 mL of the cabbage indicator into two test tubes.
- Add 5 mL of HCI (Acid) to one test tube and 5 mL of NaOH (Alkali) to the other test tube.
- Record the changes in the table below.
- Clean the test tubes and repeat for the Beetroot, Tea, Cranberry, and Turmeric indicators.
Discussion: For this experiment, we didn't use any burners. because our room is a classroom it's not a science room. so we found not to use any burners. but it still works and uses all of this to see if it's a base or an acid.
Conclusion: the experiment works. it was really fun, especially with my friends I'm working with. we were just having fun experimenting this indicator.
