amperometric titration

A method of determining the chemical composition of a solution by measur­ing the current passing through a cell containing the solution; the po­tential is held constant during the titration for both the indicator and reference electrodes, with changes in the current being measured. The cur­rent flowing through the cell is meas­ured as a function of the amount of substance being titrated.

back titration

A technique in vol­umetric analysis in which a known excess amount of a reagent is added to the solution to be estimated. The unreacted amount of the added reagent is then determined by titra­tion, allowing the amount of sub­stance in the original test solution to be calculated.
