Flashcards in 5.4 Vocab Deck (13):
1

Solute

Substance dissolved in a given solution

2

Solvent

A liquid capable of dissolving another substance (water)

3

Miscible

Can be mixed

4

Immiscible

Cannot be mixed

5

Dilute

having a low concentration or a concentration that has been reduced by admixture.

6

Concentrated

the strength of a solution, esp the amount of dissolved substance in a given volume of solvent, usually expressed in moles per cubic metre or cubic decimetre (litre).

7

Concentration

the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution.

8

Saturated solution

a solution in which no more solute can be dissolved in the solvent. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.

9

Unsaturated solution

a chemical solution in which the solute concentration is lower than its equilibrium solubility. All of the solute dissolves in the solvent.

10

Supersaturated solution

n contains more solute at a given temperature than is needed to form a saturated solution.

11

Molarity

molarity is a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.

12

Part per million (ppm)

means out of a million. Usually describes the concentration of something in water or soil. One ppm is equivalent to 1 milligram of something per liter of water (mg/l) or 1 milligram of something per kilogram soil (mg/kg).

13

Solubility

chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.
