Answer 1

Answer:

Purple cabbage solution is a natural indicator which changes its colour in an acidic, basic and neutral medium.

When we put the solution of citric acid in purple cabbage solution it turns into reddish pink which shows that solution is acidic.

When we put the solution of magnesium hydroxide in purple cabbage solution it turns into green or yellow which indicates that the solution is basic.

In the case of Sodium sulphate, the purple cabbage solution shows purple colour because sodium sulphate is a salt that is neutral\.

Hence,

we can able to classify the given solution on basis of purple cabbage solution.
