This exercise was a way of testing how effective red cabbage juice is at being an indicator. When we talk about indicators, in this unit of Chemistry, we are referring to the ability of a substance to identify if a substance is an Acid or a Base or if a substance is neutral.

Is the Cabbage juice good at differentiating Acids from Bases? Or Acids from Neutral substances Or Bases from Neutral substances? Another way of saying differentiating is 'separating' so is the cabbage juice capable of separating these solutions/chemicals?

Do we see a different colour change in the following reactions:

Cabbage Juice + Acid -->

Cabbage Juice + Base -->

Cabbage Juice + Neutral Solution -->

If we saw that the same colour was seen in all of these reactions it wouldn't be a very good indicator. So what is your conclusion? Describe on the discussion tab on this page.
