Science: Vernier - Conductimetric Titration and Gravimetric Determination of a Precipitate
by Vernier Software & Technology

Published on June 09, 2008

Overview

Students use a Conductivity Probe to measure change in conductivity during a chemical reaction and determine the equivalence point of the reaction They determine the mass of the product and calculate the molar concentration of the reactant solution.

Key Steps

    In order to find the molarity of a barium hydroxide solution, the conductivity is measured in a titration with sulfuric acid. The graph yields the equivalence point so that students can determine the unknown molarity.

    The molarity of a barium hydroxide solution is also determined by gravimetric determination by weighing the precipitate. The Periodic Table app can be used in doing the calculations.
