Definition

A technique used in chemistry to analyze substances by measuring the current that flows through a solution as the voltage is changed.

Example

Scientists often use polarography to determine the concentration of different ions in a solution.

Conversation

Have you heard about polarography in chemistry class?

Yeah, I think it's some kind of analysis method, right?

Exactly, it's used to measure current-voltage relationships in solutions.

That sounds interesting! I should read more about polarography.

Root Explanation

Polarography is formed from "polar" (from Latin "polaris", meaning of the poles) and "-graphy" (from Greek "grapho", meaning to write or record). The term refers to a method of recording electrical currents in relation to the potential difference in a solution, often used in analytical chemistry.

Memory Tip

Think of 'polar' relating to the 'poles' and '-graphy' meaning 'to write' — polarography is a method that 'records' electrical activity related to the poles.
