Back Titration in Chemistry - ThoughtCo

Oct 07, 2019  A back titration is a titration method where the concentration of an analyte is determined by reacting it with a known amount of excess reagent.The remaining excess reagent is then titrated with another, second reagent. The second titration's result shows how much of the excess reagent was used in the first titration, thus allowing the original analyte's concentration to be calculated.
