Definition

1. Noun:
   • An electrochemical method of chemical analysis: Polarography is an analytical technique that measures the current flowing through a solution as the voltage is varied. It is used to identify and quantify substances, particularly metal ions and organic compounds, based on their reduction or oxidation at a working electrode.

Usage Examples

• Noun:
  • Polarography was used to determine the concentration of lead ions in the water sample.
  • The classic experiment involves dropping mercury electrode polarography.

Advanced Usage

• "to perform polarography": to conduct an analysis using this technique.
  • The researcher will perform polarography to analyze the electrochemical properties of the compound.

Variants and Related Words

• Polarographic (adj): relating to or using polarography.
  • The polarographic data provided a clear voltammogram.
• Polarographically (adv): in a manner relating to polarography.
  • The ion was determined polarographically.

Synonyms

• Voltammetry: a broader category of electrochemical techniques that includes polarography.
