Special Features of coulometric methods:

1. Coulometric methods provide more accurate and precise results than typical methods because the electrical currents could be controlled and measured along with utmost precision.

2. These techniques are suited for both routine as well as rare analyses that included electrolytic method of determination.

3. Coulometric titrations are more popular and have the special benefits in the sense in which the tedious steps of storage, preparation and handling of standard titrants are prevented.

4. Titrations that cannot be performed through conventional methods could be simply performed coulometrically. The Titrations of large hazardous materials, titrations including unstable or hard prepared titrants like as bromine, tin (II), titanium (III), chromium (II), silver (II) etc. and titrations within molten salts could be performed.

5. In situ generation of titrants, for instance electrolytic generation of iodine used to estimate hydroquinone, antimony (III), ascorbic acid, electrolytically generated bromine used to estimate organic substances such as oxine have been found to be the most satisfactory intermediates for the estimation of various organic compounds.

6. Constant current coulometry has hugely been used than the controlled potential coulometry since the former is faster and needs simpler instrumentation and less expensive.

7. Controlled potential coulometry is a relatively sensitive technique and has selectivity.
