Question

Which form of electrochemical measurement does NOT involve electrolysis?

• A. \( \text{Coulometry} \)
• B. \( \text{Voltammetry} \)
• C. \( \text{Amperometry} \)
• D. \( \text{Potentiometry} \)

Hint:

Potentiometric methods provide electrochemical insights without requiring applied current.

Answer 1

The Correct Option is D

Potentiometry measures electrochemical potential differences without inducing electrolysis, making it ideal for pH measurement and ion-selective analysis. Other techniques involve electrolysis to determine chemical concentrations.
