  • An electrolyte is a compound that, in aqueous solution, conducts electricity. As liquids: salts, bases. When aq: salts, acids, bases.

  • HCl(aq): H+(aq) + Cl–(aq)

    NaOH(aq): Na+(aq) + OH–(aq)

    CuSO4(aq): Cu2+(aq) + SO42–(aq)

  • Acid: a compound that ionizes in water to form hydrogen ions. Base: an ionic hydroxide that dissociates in water to produce hydroxide ions.

  • By placing H in front it indicates that the compound is an acid (that H comes off as H+).

  • Dissociation occurs when a (ionic) compound breaks into its ions in water. Ionization occurs when a neutral atom or molecule is converted into an ion (e.g. by water). Ionic compounds and bases dissociate. Acids ionize.

  • HC2H3O2 is an acid; in solution it is ionized by H2O, providing ions that conduct electricity. When it’s pure,there’s no water: it can’t ionize.

  • A strong acid has a greater percentage ioniza-tion (most molecules are converted to ions).

  • The % of molecules that form ions in solution.

  • HCl was a strong acid. HC2H3O2 was weak.

  • In the lab, 1 M HCl conducted strongly, 5 M HC2H3O2 weakly. 1 M HCl had more ions.

  • HCl(aq), HNO3(aq), H2SO4(aq), HBr(aq)

    A = anion, M = metal
