• Resumen

  • Solubility equilibria are usually introduced in the general chemistry course with limited mention of the nonideal behavior of real solutions. Nonideal behavior is introduced in the qualitative analytical chemistry course in the context of gravimetry. Often this concept is left as an academic exercise with no experimental application. The determination of a solubility product constant as reported here differs from other experiments in that nonideality is taken into account through Debye-Hückel theory by making few simplifying assumptions.
