A bulk electrolysis is best performed in a three part cell in which both the auxiliary electrode and reference electrode have their own cell which connects to the cell containing the working electrode. This isolates the undesired redox events taking place at the auxiliary electrode. See more Bulk electrolysis is also known as potentiostatic coulometry or controlled potential coulometry. The experiment is a form of coulometry which generally employs a three electrode system controlled by a potentiostat. … See more The rate of such reactions/experiments is not determined by the concentration of the solution, but rather the mass transfer of the substrate in the solution to the electrode surface. Rates will … See more The sample mass, molecular mass, number of electrons in the electrode reaction, and number of electrons passed during the … See more In most three electrode experiments there are two isolated cells. One contains the auxiliary and working electrode, while the other contains the reference electrode. Strictly speaking, … See more Electrocatalytic analyzes will often mention the current efficiency or faradaic efficiency of a given process determined by a bulk electrolysis experiment. For example, if one molecule of hydrogen results from every two electrons inserted into an acidic solution then the … See more WebNov 14, 2024 · Bulk electrolysis experiments were also performed under constant-voltage to simulate potentiostatic reaction conditions (Fig. 2f ).
