Question Style in MHT CET Electrochemistry PYQs

Every question in this PDF is a single-correct MCQ. Most are numerical problems on conductivity, electrolysis or cell potential, and the rest are theory questions on batteries and cells.

Question Style	What it Tests
Electrolysis	The mass deposited at the cathode when a given current is passed for a given time through a molten salt, and the time needed to deposit copper by passing 5 ampere current
Cell potential	The standard EMF of a cell made from two electrodes, the electrode potential of an electrode at a given concentration, and the standard potential of a half-reaction from the given values
Equilibrium constant	The equilibrium constant of a redox reaction in a galvanic cell, and the correct relation between the standard cell potential and the equilibrium constant
Conductivity	The degree of dissociation of a weak acid from its molar conductivity at zero concentration, and why the conductivity of an electrolytic solution decreases on dilution
Batteries and fuel cells	The false statement about the mercury battery, and the substance that is NOT required in the construction of a fuel cell

How to Use the Electrochemistry PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 100 of the 248 questions.
Learn the Nernst equation, Faraday's laws and the relation between conductivity and molar conductivity as the three main formulas.
Remember that the SI units of resistivity, conductivity and molar conductivity are different, and check them in every problem.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
