AP®︎ Chemistry: Topic 3.8 Flashcards

A particle-level diagram showing component amounts, distribution, and interactions in a solution.

The dissolved substance and the dissolving medium, respectively.

Show concentration by the number of solute particles per equal volume of solution.

Dilute has few solute particles, concentrated has many, saturated has the maximum dissolved amount.

Concentrations should be compared using the same volume so particle counts are meaningful.

An attraction between H bonded to N, O, or F and a lone pair on N, O, or F.

A layer of solvent molecules surrounding and stabilizing a dissolved particle.

One forms ions in water and conducts electricity; the other forms no ions and does not.

One dissociates completely into ions in water; the other dissociates only partially.

The separation of an ionic compound or electrolyte into ions in solution.

Show intact molecules, with water oriented toward polar regions if intermolecular attractions exist.

An ion attracts polar water molecules, with oxygen toward cations and hydrogens toward anions.

Ionic solutes separate into ions, while molecular solutes remain intact particles in solution.
