Solubility Unit Review

Front

What is solubility?

Back

Solubility is the ability of a substance (solute) to dissolve in a solvent at a given temperature and pressure.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature.

Front

What is an unsaturated solution?

Back

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

Front

What is a supersaturated solution?

Back

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

Front

What is the solute in a sugar-water solution?

Back

Sugar is the solute in a sugar-water solution.

Front

What is the solvent in a sugar-water solution?

Back

Water is the solvent in a sugar-water solution.

Front

What is the general rule for solubility of ionic compounds in water?

Back

Most ionic compounds are soluble in water, but some, like CaCO3, are insoluble.

Front

What factors affect solubility?

Back

Temperature, pressure, and the nature of the solute and solvent affect solubility.

Front

What is the solubility of KNO3 at 40°C?

Back

The solubility of KNO3 at 40°C is approximately 50 g per 100 mL of water.
