Electrochemistry — Cells, Nernst & Faraday

CSIR-NET Chemical Sciences revision note · 10 sections · about 602 words

Exam-focused revision notes on Electrochemistry — Cells, Nernst & Faraday for CSIR-NET Chemical Sciences, GATE Chemistry and IIT-JAM — the core concepts, the formulas worth memorising, the traps that cost marks, and a quick-recall table.

Two kinds of cell

A galvanic cell turns a spontaneous reaction into electrical work; an electrolytic cell does the reverse. Getting the electrode signs right is where most marks are lost.
