Re: Help!!! Urgent!! Colour change of those natural substances as a base/acid indicat
Don't you do these experiments at school?
I can't remember them now, besides we only did cabbage, hibiscus and cranberry.
Cabbage was red in acid and blue in base, I think. I remember cranberry was reddish in everything so like, avoid it if you can. Hibiscus was yellowish, although I can't remember in what.
Sorry.

A pink hibiscus will go yellow in a basic solution, but remain pink in acidic solution. Tea is meant to go darker in basic solution, and lighter in acidic. Acidic solutions turn tumeric indicator yellow, but I'm unsure of basic solutions.
