Electrochemistry

Electrochemistry is a Chemistry chapter on the official PMDC MDCAT 2026 syllabus, contributing roughly 2 MCQs to the 45-MCQ Chemistry section. Mastering the core concepts below typically secures the full chapter weightage.

Key Concepts

• Galvanic vs electrolytic cells
• Standard electrode potential
• Nernst equation
• Faraday's laws
• Corrosion

How Electrochemistry Is Tested

MDCAT questions on Electrochemistry are a mix of recall (definitions, classifications), application (predict outcomes, interpret diagrams), and basic numerical/analytical reasoning. PMDC papers from 2020–2025 emphasized the concepts above; older UHS papers (2008–2019) tested them too, with slight variations in question framing.
