Flashcards: Fundamentals of Mixtures and Solutions — 10 cartões

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.
