colour. Paheli added 2 drops of solution ‘B’to her test tube and got green colour. Golu added 2 drops

of solution ‘C but could not get any change in colour. Suggest the possible cause for the variation in

their results

Please tell proper answer​

Answer 1

Explanation:

China rose is a natural indicator which changes acid to pink colour, base to green colour and neutral solutions do not show any changes. 

So, the solution A is an acid, B is a base and C is neutral.
