Final answer:
The terms 'concentrated' and 'dilute' describe the relative amount of solute in a solution, with concentrated having more solute and dilute having less. These terms precede more precise measurements of concentration in solution chemistry.
Step-by-step explanation:
The terms 'concentrated' and 'dilute' refer to the relative amounts of solute in a solution. A concentrated solution has a large amount of solute in a given amount of solvent, while a dilute solution has a smaller amount of solute. For example, when you purchase a frozen juice concentrate and mix it with water as instructed, you are diluting the concentrate to create a dilute juice beverage. Conversely, the undiluted frozen concentrate represents a concentrated solution.
In the context of solution chemistry, these qualitative terms often precede more precise, quantitative expressions of concentration such as molarity, molality, or percent concentration. Understanding the difference between concentrated and dilute solutions is crucial for many applications, including laboratory preparations, industrial processes, and mixing beverages at home.
