Chemistry: Solutions Vocabulary

Alloy

A solid solution of metals (Ex: Brass)

Concentration

A ratio of solute to solvent-- the amount of solute in a solution

Electrolyte

Solutions that carry an electric current

Emulsifying agent

something that allows polar and non-polar substances to mix. Ex: soap, eggs, Soy Lecithin

Immiscible

Two gases/liquids that will NOT form a solution-- must be in the SAME state of matter

Insoluble

will NOT dissolve in -- ex: sand+water

Miscible

refers to two gases/liquids that WILL form a solution; more specific than ‘soluble’ Ex: food coloring, water, etc.

Supersaturated

Over full

suspension

appears uniform while being stirred, but settles over time. Ex: muddy water

Unsaturated

Could hold more; emptier
