What is the important difference between how concentration and solubility are measured?

Answer 1

The important difference between how concentration and solubility are measured lies in what they refer to.

Concentration refers to the amount of a substance (solute) present in a given quantity of another substance (solvent or solution). Concentration can be measured in various ways, such as molarity (moles of solute per liter of solution), mass percentage, or parts per million (ppm).

On the other hand, solubility is a measure of how much of a solute can dissolve in a given amount of solvent to form a saturated solution under specific conditions (temperature and pressure). Solubility is typically expressed as the maximum quantity of solute (in grams) that can dissolve in a fixed amount of solvent (usually in 100 grams or per liter) to form a saturated solution.

Therefore, concentration refers to the actual amount of solute present in a solution, while solubility refers to the maximum amount that can dissolve in a specific amount of solvent.

Answer 2

Concentration is measured as the amount of solute present in a given volume of solution (e.g. moles per liter), while solubility is measured as the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure. Concentration is a property of the solution, while solubility is a property of the solute in a particular solvent.

Answer 3

Remember the distinction between concentration and solubility. Concentration is measured in grams of solute per 100 mL of solution (g/100 mL solution), but solubility is measured in grams of solute per 100 mL of solvent(g/100 mL solvent). Different solutes have different solubility's, as Table 1 shows.
