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

Answer:

Blue litmus paper is dipped in a solution, it remains blue; this means that the solution is either basic or neutral. Because basic and neutral solutions does not change the colour of the blue litmus. We can check it by putting a drop of the solution on red litmus paper. If the red litmus paper changes into blue then it shows the solution is basic and if it does not change the colour, then it is neutral by nature.
