Question

In controlled cathode potential electrolysis, the third electrode used is
a) working electrode
b) reference electrode
c) counter electrode
d) auxillary electrode​

Answer 1

Answer:

Explanation:

In chemical analysis: Electrogravimetry. This method employs an electric current to deposit a solid on an electrode from a solution. Normally the deposit is a metallic plate that has formed from the corresponding metallic ions in the solution; however, other electrode coatings also can be formed.In a controlled potential electrolysis (CPE) experiment, the working electrode is held at a constant potential until the solution is exhaustively electrolyzed.
