Question

You have 4 containers, labeled A, B, C, and D, filled with clear and colorless solutions. Explain how you can determine (no tasting allowed) the contents of the beakers. The possibilities are distilled water, 1 M C12H22O11 solution, 1M NaCl solution, 1M HCl solution, and 1M NaOH solution.

Answer 1

Using blue and red litmus paper.

Step-by-step explanation:

if we test all the solutions with blue and red litmus paper, we will know which solution is water and which solution is not water because blue and red litmus paper determined the pH of the solution. The pH of the water is neutral so it can't change its colour while on the other hand, the other solution change their colour due to acidic or basic nature of the solution so in this way we can determine the chemicals in the solution without tasting it.
