Transcript of Cabbage Chemistry
Boiling pot of water
Pine Sol (lemon)
Apple 1. Grate the small red cabbage and place the pieces in a glass bowl 2. Pour boiling water into the bowl just to cover the cabbage. 3. Leave the cabbage steeping until the mixture is room temperature. the liquid should be red in color. 4. Place a strainer over a collection bowl and pour the mixture through the strainer to remove pieces of cabbage. 5. now you should have a clear liquid that will be either purple or blue. The color of the liquid should change depending upon the Ph. 6.Set aside your indicator solution, you will use it as your "stock" solution for your experiment. 7.Next you will test various household items. ( be sure to use separate containers for each solution. You don't want to mix chemicals that don't go together. 8.Now fill about half of your cup with your indicator. 9.Add drops of a liquid you want to test until you see a change in color. 10.Record the Ph of each item and a description in a data table. I used other variables in my experiment other than cabbage i also used apple peelings and red onion skins. I used this chart to determine the Ph balance of my items: Conclusion In conclusion my hypothesis was incorrect the items changed more color in the cabbage indicator, I learned that depending on whether the variables were acid or alkaline determined the Ph balance.
