Mixtures vs Pure Substances
Pure substances have fixed composition; mixtures do not.
Solutes — role?
Dissolved substances in a solution.
Separation methods — example?
Filtration, distillation, chromatography, evaporation.
Saturated vs Unsaturated
Saturated: maximum solute at given temp; unsaturated: less than maximum.
Qualitative vs Quantitative
Qualitative: describes properties; Quantitative: provides measurements.
Homogeneous mixture — also?
Solution with uniform composition.
Solvent — role?
Dissolves the solute.
Distillation — mechanism?
Separates by boiling point differences.
Supersaturated — unstable?
Yes, excess solute can crystallize.
Pure substance — melting point?
Fixed and specific.
