What does it mean to 'dilute' a solution?

Diluting a solution refers to the process of reducing its concentration, which makes it less potent or irritant. When a solution is diluted, additional solvent—often water—is added. This increases the volume of the solution, while the amount of solute (the substance being dissolved) remains constant. As a result, the concentration of the solute decreases, which can lead to a reduction in its irritating properties or potency.

In various contexts such as medicine or chemistry, diluting might be necessary to ensure safety and efficacy when administering medications or conducting experiments. Hence, option B accurately describes the outcome of the dilution process.
