Section 1

📖

Lecture & walkthrough

The complete written lesson — redox & oxidation numbers, oxidising/reducing agents, balancing by half-reactions, galvanic cells, the electrochemical series, EMF, electrolysis and Faraday's laws.

12 sections · ~25 min read

As you scroll, a live D3 panel animates every idea: electron transfer, half-reactions, the Daniell cell with flowing electrons, the electrochemical series, electrolysis, and an interactive cell builder where you pick two electrodes and read off the EMF.

Section 3

⚗️

Practical experiment

Build a Daniell cell in 3D — a Zn rod in ZnSO₄ and a Cu rod in blue CuSO₄, joined by a salt bridge and wired to a voltmeter. Set [Cu²⁺], watch the electrons flow Zn → Cu and the ions migrate, then plot the EMF vs log[Cu²⁺] Nernst line live with D3. Tap any part for an inspector + Ask AI.
