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.
Since solution A turns China rose colour to dark pink hence Solution A is an acidic solution. whereas solution B turns China rose colour to green colour hence Solution B is a basic solution. And Solution C did not change the colour of china rose Solution, so it is a neutral solution.
