Question

Three test tubes (1,2,3) contain China rose solution that was pink in colour. On addition of two drops of solution 'A' to test tube 1, dark pink colour appears. When two drops of solution B are added to test tube 2, the colour turns to green. On addition of two drops of solution C to test tube 3, there is no change in colour. Why do you think these changes in colour happens?

these changes in colour happen due to chemical reaction of 2 solutions
china rose reacted with the solution and changed its colour

Answer 2

solution B is basic

and solution C is nuetral
