Introduction/Background:

 

A solution conducts electricity due to the presence of ions. But, when a strong electrolyte is added to another strong electrolyte, a precipitate will form and the ion concentration and conductivity will decrease accordingly. Continued addition of the second electrolyte continues to lower the ion concentration and the conductivity until the equivalence point is reached. At the equivalence point, all the ions are removed and conductivity is at its minimum. But, conductivity increases if more of the second electrolyte is added after the equivalence point, for ions are still being added to the solution from the second electrolyte.

 

Purpose:

 

To determine how conductometry can help obtain the concentration of a Ba(OH)2 solution.
