Aim: To make acid base indicators out of everyday indicators
Method:For the cabbage Chop the cabbage into small pieces until you have enough to fill 2 cups,Place the cabbage in a large beaker and add water to cover the cabbage.In a large beaker and add water to cover the cabbage,Boil over a Bunsen burner for at least ten mins for the colour to leach out of the cabbage,Filter out the plant material to obtain a red-purple-bluish coloured liquid.This liquid is at about ph 7.(The exact colour you get depends on the ph of the water,Place in a small beaker and leave to one side,Repeat this method acid for the beetroot.

Results:
Disscussion: We boiled the cabbage,We then put the cabbage indicator into two spottng tile holes.we then dropped HCI(acid) into each of the indicators for the rest we put in naOH(Alakali base) we also did this with the other indicaors-Tea,cranberry juice,tumeric,beetroot
Conclusion:in conclusion this expiriment was great to see what colours would occur using base and acid using everyday household products
