Method:
Chop the cabbage int small pieces until you have enough to fill 2 cups. Place the cabbage in a large beaker and add water to cover the cabbage. Boil over a Bunsen burner for at least ten minutes for colours to leach out of the cabbages. Filter out the plant material to obtain a red-purple-bluish coloured liquid. This liquid is at about hp 7 [the exact colour you get depends on the ph of the water.
Places in a small beakers and leave to one side. repeat this method for beetroot.
Result
Discussion
My group had decide to experiment on acid and base for cabbage, the acid made the indicator red. Then the base made the indicator green. If you mix it together it made up different colours showing whether is basic or acidic.
Conclusion
This is the after finishing and is was a success. By mixing the acid-base with indicator for what we were hoping for.
