Today I did chemistry with Katie. We were looking for ingredients to see if they were neutral, a base or an acid. This is what we had to do:
1. Get red cabbage and cut it up.
2. Put the cabbage into the bowl.
3. Drain the water into a bowl and leave it for 45minutes after the water should turn purple.
4. Chuck the cabbage out and pour the water into a few glasses.
5. Get ingredients that you want to test.
6. Pour or tip the ingredients into the purple water
7. If they go darker ( blue ) they are a base. If they go lighter ( red orange yellow) they are an acid, but if they turn green they are neutral.
