Blue litmus paper is dipped in a solution. It remains blue. What is the nature of the solution? Explain.

Answer:
A solution which does not change the colour of blue litmus paper can be either basic or neutral in nature. The nature of the solution can be confirmed by placing a drop on red litmus paper. If the colour change to blue then the solution is basic and if no colour change is observed, the solution is neutral in nature.
