Advantages of Coulometric Titrations:

i) Preparation, standardisation and storage of standard solutions are not essential in coulometrc titrations. This is meaningful especially for preparation of unstable reagents like as dipositive silver ions, tri-positive manganese ions, chlorine, bromine, titanium (III) etc. that could be produced in situ, because the conventional analysis cannot handle these reagents.

ii) It is simple to handle small quantities of reagents through coulometric titrations.  Through proper choice of current, micro quantities of substance could be analysed along with greater accuracy and ease.

iii) A single constant current source could be used to generate precipitating, redox and complexing reagents.

iv) Coulometric titrations could readily be adapted to automatic titrations as the current control is simply completed.

v) A number of automatic coulometric titrators are readily available within the market to monitor environmental pollutant.

vi) In chloride titrator silver (I) ion is produced coulometrically.

vii) Within sulphurdioxide monitors, anodically produced bromine oxidises the analyte to sulphate ions.

viii) In carbon dioxide monitors, in that the gas stream absorbed in monoethanolamine is titrated along with coulometrically generated base.

ix) Within water titrators - Karl Fischer reagent is generated electrolytically to determine trace level concentrations of water content /moisture.
