Q. On adding a few drops of universal indicator solution to three unknown colourless solutions P, Q, and R taken separately in three test-tubes shown in the diagrams, a student observed the changes in colour as green in solution P, red solution Q and violet in solution R.

The decreasing order of the pH of the three solution is :
(1) P > Q > R
(2) R > P > Q
(3) Q > P > R
(4) R > Q > P

Few drops of universal indicator are added to three colourless solutions taken separately in three test tubes labeled as P, Q, R respectively. The colour change of the solutions are marked in the following figures:

Arrange the test tubes in a descending order as per the pH value?

Abhishek was working in his chemistry lab. He had three test tubes containing three different solutions P, Q and R. When he added few drops of solution R to the test tube containing solution P, solution P turned pink from colorless. After this he added few drops of solution Q to the test tube containing solution P, it then became colorless again. Explain the observations and identify P, Q and R. [5 MARKS]
