You have been provided with three test tubes. One of them contains distilled water and the other two contain an acidic solution and a basic solution, respectively. If you are given only red litmus paper, how will you identify the contents of each test tube?


Question 1. You have been provided with three test tubes. One of them contains distilled water and the other two contain an acidic solution and a basic solution, respectively. If you are given only red litmus paper, how will you identify the contents of each test tube?
Answer: If the colour of red litmus does not change then it is acid. If the colour of red litmus changes to blue then it is base. If there is slight change in the colour of red litmus (such as purple) then it is distilled water.

    This is actually incorrect. The right thing to do would be to take a few drops of the litmus paper and take drops from the solutions and keep dropping in onto different prices until one changes colour to blue. This solution is basic. Keep it aside. Now take that same piece of litmus (the blue one) and drop the other two onto it. If it doesn't change colour, it's water. If it turns back to red it's acidic.
