The purpose of this lab was to use to see if conductivity could be used to determine stoichiometric coefficients in a chemical reaction. Ionic compounds separate in aqueous solutions to become ions, which are accountable for the ability of solutions to conduct electricity. If a solution has a greater ion concentration or their ions have a greater charge, the electrical conductivity increases. When two solutions combine in a ratio that is not their stoichiometric ratio, there will be extra ions in one solution, which will then increase the conductivity. When the two solutions are combined in their stoichiometric ratio, then their conductivity will be the least.
