Final answer:
The terms 'concentrated' and 'dilute' are qualitative but not the only ways to describe solution concentration; quantitative methods like molarity and percent composition are also fundamental.
Step-by-step explanation:
The statement that the terms “concentrated” and “dilute” are only qualitative descriptions of the amount of solute in a solution is false. Although these terms do provide a qualitative way of expressing the relative concentration of a solution, quantitative methods are also essential and widely used in chemistry. To define a solution's concentration precisely, quantitative measurements such as moles per liter (molarity), grams per liter, or percent concentration are necessary.
These methods allow for an exact specification of how much solute is dissolved in a given amount of solvent, as opposed to the relative terms “dilute” (little solute) or “concentrated” (a large amount of solute), which can be vague and subjective.
