Titration is a method to determine the concentration of a substance in the solution by making it react with a solution of known concentration of other substance, just beyond the point where the reaction between both the substances completes. In precipitation reactions, on the reaction of the reactants, an insoluble end product is formed which precipitates out from the solution.
The chemical reaction for the formation of barium sulfate on the reaction of barium chloride and potassium sulfate is,
Thus, one mole of barium chloride reacts with one mole of potassium sulfate to form a mole of barium sulfate.
