Acid or Base Investigation.

Our latest experiment was to use red cabbage juice as an indicator to 
identify whether common household products are acids or bases.

We added the red cabbage juice to each ingredient
and watched to see the colour of the final product.

Pink = Acid
Blue = Base
Purple (no change) = Neutral

Watch our investigation in the video below.

Our Final Results:
