Properties of Solutions and Concentration Flashcard

A solution is a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another (solvent).

A solute is the substance that is dissolved in a solution.

A solvent is the substance in which the solute is dissolved to form a solution.

An unsaturated solution is one that can still dissolve more solute at a given temperature.

A saturated solution is one that has dissolved the maximum amount of solute at a given temperature.

A supersaturated solution contains more solute than can normally be dissolved at a given temperature.

Generally, for most solids, solubility increases with temperature, while for gases, solubility decreases with increasing temperature.

Concentration is the amount of solute present in a given volume of solution, often expressed in molarity (moles per liter).

Agitation increases the rate at which solutes dissolve in a solvent.

SO₂ is the least soluble solute at 90 ⁰C.
