Properties of Solutions and Concentration Flashcard

Front

What is a solution?

Back

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

Front

What is a solute?

Back

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

Front

What is a solvent?

Back

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

Front

What does it mean if a solution is unsaturated?

Back

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

Front

What does it mean if a solution is saturated?

Back

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

Front

What does it mean if a solution is supersaturated?

Back

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

Front

How does temperature affect solubility?

Back

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

Front

What is concentration?

Back

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

Front

What is the effect of agitation on solubility?

Back

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

What is the least soluble solute at 90 ⁰C among SO₂, KClO₃, KI, and HCl?

Back

SO₂ is the least soluble solute at 90 ⁰C.
