Electrochemistry: Class 12 Chemistry (MP Board) important questions and practice
Electrochemistry is chapter 2 of 10 in MP Board Class 12 Chemistry. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Electrochemical cells and the Daniell cell; electrode potential and SHE
- Nernst equation and equilibrium constant from cell EMF
- Gibbs energy and cell potential
- Conductance: conductivity, molar conductivity, variation with concentration, Kohlrausch's law
- Electrolytic cells and Faraday's laws of electrolysis
- Batteries: primary (dry cell, mercury cell) and secondary (lead storage, Ni-Cd); fuel cells and corrosion
What examiners usually ask
- Calculate the EMF of the cell Zn|Zn2+(0.1 M)||Cu2+(0.01 M)|Cu at 298 K given the standard electrode potentials
- State Kohlrausch's law and explain how it is used to find the limiting molar conductivity of a weak electrolyte like acetic acid
- How much charge is required to reduce 1 mol of MnO4- to Mn2+? Write the reactions in the lead storage battery during discharge
Exam tip
Write the Nernst equation with the correct n and concentration ratio (products over reactants) and the relation delta G = -nFE; also distinguish conductivity (decreases with dilution) from molar conductivity (increases with dilution) because this contrast is asked repeatedly.
