A concentration unit of a solution expressed as moles of a solute dissolved per liter of solution.

Question 7

What is solubility?

Answer 7

The ability of one substance to dissolve into another at a given temperature and pressure; expressed in terms of the amount of solute that will dissolve in a given amount of solvent to produce a saturated solution.

Answer 10

The separating of a molecule into simpler molecules, atoms, radicals, or ions.

Question 11

What is hydration?

Answer 11

The strong affinity of water molecules for particles of dissolved or suspended substances that cause electrolytic dissociation.

Question 12

What is saturated solution?

Answer 12

A solution that cannot dissolve any more solute under the given conditions.

Question 13

What is unsaturated solution?

Answer 13

A solution that contains less solute than a saturated solution and that is able to dissolve additional solute.

Question 14

What is supersaturated solution?

Answer 14

A solution holding more dissolved solute than what is required to reach equilibrium at a given temperature.

Question 15

What is solubility equilibrium?

Answer 15

The physical state in which the opposing processes of dissolution and crystallization of a solute occur at equal rates.

An ion consisting of a proton combined with a molecule of water; H3O+

Question 20

What is colligative property?

Answer 20

A property of a substance or system that is determined by the number of particles present in the system but independent of the properties of the particles themselves.
