...indicator. (Or, the juice of a cabbage. :) )
it is an indicator.
cabbage juice is a natural pH indicator
anthocyanin
An artificial indicator is one that is chemically made and you cannot create from Natural Resources e.g. cabbage juice
It is an acid, because Red Cabbage Juice is an indicator, and White Vinegar is an acid.
it turns greenish yellow if it is added to a base
If the pH of a detergent is usyally greater then 7 the juice of red cabbage become blue to green in this solution.
yes I've done it for a science project
Because tooth paste is a base because anything that turns a blue or green when mixed with red cabbage juice(indicator) is a base.
The red-cabbage indicator smells like cabbage, nothing else...
It will turn either blue or green, both a hue of blue. The reason of this is that Red Cabbage Juice is an indicator, which is used to see wether an object or chemical is an acid or a base. If the object is an acid it will turn a hue of pink, and if it is a base, it will turn a hue of blue. Which is why baking soda mixed with Red Cabbage Juice will turn blue or green.
