Question

you have three colourless solutions and only that Litmus Paper then how can you identify the solution in which one is acid one is base and manager one is neutral by using only red Litmus​

Answer 1

Given

☞ Three colourless solutions

☞ Red litmus paper

To identify

☞ Acidic Solution

☞ Basic Solution

☞ Neutral Solution

Experiment

★ Case 1

Dip the red litmus paper in first solution. If the paper turns blue, then the solution is basic in nature. Cut the blue part from the litmus paper

★ Case 2

Dip the blue part of the litmus paper (which we have obtained in the above experiment) in the second solution. If the paper turns to red, then the solution is acidic

★ Case 3

Dip the red litmus paper or blue litmus paper in the third solution. If there is no change in colour, then the solution is neutral
