Question:  How can conductometry help obtain the concentration of a Ba(OH)2 solution?

Purpose:  The purpose of this experiment is to measure the conductivity of a barium hydroxide solution to determine the concentration by titrating it with a solution of H2SO4 of known concentration.

A titration determines the amount, or concentration, of a reactant in a chemical reaction.  In this experiment, the equivalence point is determined.  Higher ion concentration results in higher conductivity.  The continued addition of a second electrolyte lowers the ion concentration and the conductivity until the equivalence point is reached.  All ions are removed and the conductivity is at its minimum value.
