A student prepared solutions of (i) an acid and (ii) a base in two separate beakers. She forgot to label the solutions and litmus paper is not available in the laboratory. Since both the solutions are colourless, how will she distinguish between the two ?

These solutions can be tested by using universal indicators. If the solution (i) turns red it is an acid and If the solution (ii) remains colourless it is a base.
