POLAROGRAM Meaning and
Definition
-
A polarogram refers to a graphical representation of the polarographic method, which is an electrochemical technique used in the qualitative and quantitative analysis of various substances. Specifically, it is a voltammetric measurement method that investigates the behavior of ions or molecules in solution. The polarogram is obtained by plotting the current response on the y-axis against the applied potential on the x-axis.
In a polarogram, a working electrode is immersed in an electrolytic solution containing the analyte of interest. Through the application of a potential, the redox reactions involving the analyte take place at the electrode surface, resulting in changes in current. This current-potential relationship provides valuable insight into the identity, concentration, and reduction or oxidation potential of the tested species. By analyzing the shape, location, and height of the peaks or waves on the polarogram, information about the analyte's chemical properties and behaviour can be deduced.
Polarograms are commonly used in various fields like pharmaceutical analysis, environmental monitoring, and industrial processes. The technique allows for the determination of trace amounts of targeted substances, making it highly sensitive. Polarography has proven particularly useful in the analysis of metals, certain organic compounds, and in studying electrode processes. The polarogram, as a visual representation of the voltammetric response, aids researchers and analysts in interpreting and drawing conclusions about the specific analyte under investigation.

Etymology of POLAROGRAM
The word "polarogram" is derived from two main components: "polar" and "gram".
- "Polar" comes from the Greek word "pólos" (πόλος), meaning "axis" or "pole". In this context, it refers to the concept of polarity, which relates to the electrical charges or poles present in an electrochemical system.
- "Gram" comes from the Greek word "grámma" (γράμμα), meaning "letter" or "written mark". It is commonly used as a combining form in scientific terminology to indicate something related to writing or recording.
Therefore, the word "polarogram" combines these elements to describe a graphical representation or recording of polarized electrical currents or potentials observed during polarography, an electrochemical technique used for studying chemical species.
