Indicator electrode
The electrode typically made of mercury and serves as the site for the electrochemical reaction with the analyte in classic polarography is the indicator electrode.
Explanation:
Classic polarography:
Classic polarography is an electroanalytical technique that involves measuring the current flowing through a solution as a function of the applied potential. This technique is widely used in analytical chemistry for the determination of various analytes.
Indicator electrode:
In classic polarography, the indicator electrode is typically made of mercury. This electrode serves as the site for the electrochemical reaction with the analyte. The use of a mercury electrode allows for a wide range of analytes to be detected and quantified with high sensitivity and accuracy.
Function of the indicator electrode:
The indicator electrode serves as the working electrode in the classic polarography setup. It is responsible for initiating the electrochemical reaction with the analyte present in the solution. The mercury electrode provides a stable and reproducible surface for the electrochemical reaction to take place, ensuring accurate measurements of the analyte concentration.
Importance of the indicator electrode:
The choice of the indicator electrode, particularly one made of mercury, is crucial in classic polarography as it directly influences the sensitivity and reliability of the analytical measurements. The mercury electrode offers several advantages, such as low background current, wide potential window, and high sensitivity, making it ideal for a wide range of analytes.
In conclusion, the indicator electrode made of mercury plays a critical role in classic polarography by serving as the site for the electrochemical reaction with the analyte, enabling accurate and sensitive determination of analyte concentrations.
