Electrochemistry — NEET/JEE Questions, Notes & Weightage
Class 12 Physical Chemistry NEET weightage: Very High 217 questions
Covers galvanic cells, the Nernst equation, conductance, Kohlrausch's law, and electrolysis (Faraday's laws). One of the highest-yield Class 12 Chemistry chapters — Nernst-equation numericals and EMF/cell-potential questions appear in almost every NEET/JEE paper.

Frequently asked questions
What is the single most important formula in this chapter?
The Nernst equation, used to calculate cell potential under non-standard conditions, is this chapter's most frequently applied and highest-value formula.
Are Faraday's laws of electrolysis tested numerically?
Yes — calculating the mass of substance deposited/liberated given current and time is a standard, recurring numerical type.
