Wikipedia     Advertizing ▼      There are two basic categories
of coulometric techniques. Potentiostatic coulometry involves
holding the electric potential constant during the reaction
using a potentiostat. The other, called coulometric titration or
amperostatic coulometry, keeps the current (measured in amperes)
constant using an amperostat.     Potentiostatic coulometry
Potentiostatic coulometry is a technique most commonly referred
to as "bulk electrolysis". The working electrode is kept at a
constant potential and the current that flows through the
circuit is measured. This constant potential is applied long
enough to fully reduce or oxidize all of the substrate in a
given solution. As the substrate is consumed, the current also
decreases, approaching zero when the conversion is complete. The

electrode reaction, and number of electr
