Part IV Cabbage Juice Indicator Chop cabbage into small pieces until you have about 2 cups of chopped cabbage. Boil for at least ten minutes to allow time for the color to leach out of the cabbage. Allow it to cool for 15 min • Filter out the plant material to obtain a red-purple-bluish colored liquid. 1. Add 1-2 drops of cabbage juice into a small bowl 2. Add 3-5 drops of vinegar into the bowl with the cabbage juice 3. Observe Is this a chemical change or physical change? Explain? Store the excess cabbage juice in your refrigerator, you will need them for future experiments.
