Answer 2

In polarographic measurements when reference electrode acts as an anode then cations present in the solution experience (b) oxidation and formation of amalgam.

Explanation:

• Anodic stripping  polarography  is extremely sensitive to experimental circumstances, which we must constantly monitor if we want accurate and exact results.
• The size of the hanging Hg drop, the area of the mercury film, the deposition duration, the rest time, the rate of stirring, and the scan rate during the stripping step are all important variables.
• For metals that produce amalgams with mercury, anodic stripping voltammetry is particularly beneficial.
