Green Solutions a green solution of indicator was added to a sample of spring water. the resulting solution was yellow.?

Question by Mckayla Newman: a green solution of indicator was added to a sample of spring water. the resulting solution was yellow.?
Was the observed change due to a physical or chemical change? Why? And EXPLAIN!

Need help on this one.

Best answer:

Answer by Big_Kid
a color change using an indicator is a chemical change.
Why? It’s because chemical changes cannot be reversed using physical processes (such as heating or the use of filters). You can’t filter out the yellow solution to get back your green solution.
