Explanation:
First i will dip the litmus into the distilled water which makes no change. Then I will dip the red litmus into basic solution which turns it into blue litmus and indicate that the solution is basic in nature. After this I will dip the blue litmus into acidic solution which turns it into red which indicates the acidity of the solution..
