Question

Rohan conducted an experiment where he used China rose indicator in Solution I,II and III and got following colour changes. What could be the possible solutions as indicated in the test tubes I,II and III​

Answer 1

Answer:

China rose indicator turns magenta in acidic solution, no change in neutral solution and green in basic solution. Therefore, test tube I contains an acidic solution (lemon juice), test tube III contains basic solution (lime water). As test tube II shows no change in colour so, it contains a neutral solution (sugar solution)
