(40) GCSE Chemistry Revision "Concentration of Solutions"

Concentration

The mass of a solute in a given volume of solution, typically measured in grams per decimeter cubed.

Solute

A chemical that is dissolved in a solvent.

Solvent

A substance, often a liquid, in which a solute is dissolved to form a solution; commonly, water is used as a solvent.

Grams per Decimeter Cubed (g/dm³)

The unit of concentration that signifies how many grams of solute are present in one decimeter cubed of solution.

Mass

The amount of a substance in grams.

Volume

The space occupied by a substance, measured in decimeters cubed in this context.

Triangle method for concentration

A visual tool used to remember the relationships between mass, volume, and concentration: Concentration = Mass / Volume.

Increasing solute mass effect on concentration

If the mass of the solute is increased while keeping the volume constant, the concentration increases.

Increasing solution volume effect on concentration

If the volume of the solution is increased while keeping the mass of solute constant, the concentration decreases.

Decimeters cubed (dm³)

A volume measurement equivalent to one liter, commonly used in chemistry.
