A student performed following two activities in school laboratory:
Activity 1: Addition of zinc dust into copper sulphate solution taken in a test tube.
Activity 2: Addition of an iron nail into copper sulphate solution taken in a test tube. He noted down his observations and concluded that chemical reaction occurs in both the cases based on the observed colour change of the resulting solution.
What was the initial colour of the solution?
