Question

Acidic,basic and natural solutions are given in three test tubes and you are given a strip of blue litmus ?how will you identify the nature of three solutions ?​

Answer 1

Answer:

We will identify by the color change when the solutions dropped on the litmus paper then the Acidic solution will change the Blue litmus into Red and Red litmus into Blue and Neutral solution will not change the color of litmus.

Answer 2

Answer:

First dip the blue litmus in one of the beakers. if the solution turns red, this means it is an acidic solution.

now dip this reddened litmus in one of the solutions, and if, it turns blue again, this means this is a basic solution. and if, there's no change in litmus, it is neutral.
