Question

Boojho, Paheli and their friend Golu were provided with a test tube each containing China rose solution which was pink in colour. Boojho added two drops of solution ‘A’ in his test tube and got dark pink 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.

Answer 1

A’ is an acidic solution, China rose solution turns dark pink in acids. ‘B’ is a basic solution since China's rose solution turns green in the basic solution. ‘C’ is a neutral solution hence there is no change in the colour of the China rose solution.
