Free unofficial High School Chemistry Battery & Electrolysis Quiz
This app is an independently created 4-choice quiz for practicing high school chemistry topics such as redox reactions, galvanic cells, electrolysis, electrode reactions, Faraday’s law, deposited mass, and generated gas volume.
All questions, answer choices, explanations, and diagrams are original. The app is designed for daily review and timed practice, not as a reproduction of textbook, exam, worksheet, or prep-school materials.

Original hints and diagrams
Hints are generated for the current question and include original SVG-style diagrams for electron transfer, cell electrodes, electrolysis, and Faraday’s law calculation flow.
Long-tail practice topics covered
The quiz is organized around search and study needs such as oxidation-number practice, identifying oxidizing and reducing agents, electron flow in galvanic cells, anode/cathode differences, writing electrode reactions, Faraday calculation steps, deposited mass, generated gas volume, electrolysis time, and current calculations.
Each question is short, original, and suited for quick review. Hints focus on the reasoning path: track electrons, identify the electrode, convert charge to mol electrons, then use the coefficient in the electrode reaction.
Useful for regular tests and chemistry review
You can use the 10-question basic course for a quick check, then move to calculation-heavy Faraday courses and the 100-question electrochemistry mix. The ranking and My Page features help you review missed questions repeatedly.
