IB DP Chemistry Voltaic Cells Pre-Lab Notes and Practical Guide 2026

This pre-lab resource provides students with structured preparation for investigations involving voltaic (galvanic) cells. It is designed to give learners a clear overview of the principles, methods, and safety considerations required before entering the laboratory to explore electrochemical cells, standard electrode potentials, and energy transfer.

Keeping it Simple
This pre-lab pack offers a concise, accessible introduction to voltaic cells and electrochemical principles. It focuses on essential concepts and practical steps without dense theory, helping students build confidence with cell construction, measurement techniques, and linking observations to underlying chemical ideas before they begin hands-on work.
