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 1

Answer:

if red litmus paper turns blue it is acidic solution when their is no change observed it is a base

Answer 2

Hey !!!

To check the contents of each test tube :

We are provided with only red litmus paper.

• Put the red litmus paper in all test tubes one by one,the solution which will change it into blue colour, it means it is a basic solution ( because a basic solution changes red litmus paper into blue ).

Now , we are left with only two test tubes.

• Put that blue litmus paper in both the test tubes one by one ,the solution which will change it into red colour means it is an acidic solution ( because an acidic solution changes blue litmus paper into red ).

• The left tube is distilled water. We can also check it by putting litmus paper. Hence, no change will be observed.
