Current flow due to electrostatic attraction of analyte ions by the electrodes is reduced to a negligible level by a presence of high concentration of supporting electrolytes. It also reduces the net current and decrease the rate of cationic analyte at the negative electrode surface.
In polarography, a higher concentration of electrolyte is added compared to the analyte to enhance conductivity and ensure a stable environment for the reduction or oxidation reactions at the electrode surface. This excess electrolyte minimizes the effects of concentration polarization and helps maintain a consistent ionic strength, which is crucial for accurate measurements. Additionally, a higher electrolyte concentration provides a background current that is necessary for distinguishing the current due to the analyte.
Mercury is commonly used in polarography due to its unique properties, such as low melting point, high density, and wide electrochemical potential window. These characteristics make mercury electrodes stable and suitable for polarographic measurements. Additionally, mercury forms amalgams with other metals, allowing for a wide range of applications in electrochemistry.
It is an electrolyte
The dissociation is not so important.
Non ionic, non electrolyte

I'm not sure what an electrolyte actually is. Please describe the characteristics of an electrolyte succinctly.
Polarography is a type of voltammetry that measures current at varying potentials to analyze electroactive species, while amperometry measures current at a constant potential to study concentration changes over time. In polarography, the potential is scanned to generate a voltammogram, while amperometry uses a fixed potential to monitor changes in current.
Mercury is commonly used in polarography due to its unique properties, such as low melting point, high density, and wide electrochemical potential window. These characteristics make mercury electrodes stable and suitable for polarographic measurements. Additionally, mercury forms amalgams with other metals, allowing for a wide range of applications in electrochemistry.

To effectively test the electrolyte levels in drinks, one can use a digital electrolyte analyzer or a handheld electrolyte meter. These devices measure the concentration of electrolytes such as sodium, potassium, and chloride in the drink sample. Alternatively, one can also use chemical test strips specifically designed to detect electrolytes in liquids.
