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?
The student can use other indicator; like phenolphthalein or methyl orange to check the acidity or alkalinity of a particular solution. The student can also use turmeric powder to check the solutions. It is mentioned that litmus paper is not available. So, we can assume that the laboratory may have other indicators.
