NCERT Class 12 Chemistry Chapter 2 Electrochemistry Test Mock Test
This free online test covers Chapter 2, Electrochemistry, from the NCERT Class 12 Chemistry-I textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.A Daniell cell has a potential of 1.1 V when the ion concentrations are unity. If an external opposing potential greater than 1.1 V is applied to it, then:
- AThe cell potential rises above 1.1 V but the reaction direction stays the same
- BNo current flows at all, whatever the value of the applied potential
- CElectrons flow from copper to zinc, zinc is deposited at the zinc electrode and copper dissolves, so the cell works as an electrolytic cell
- DThe reaction continues in the original direction but faster, since more energy is supplied
Q2.By the accepted convention for representing a galvanic cell, the emf of the cell is given by:
- AThe sum of the two half-cell potentials, whichever way they are written
- BThe potential of the half-cell on the left hand side minus that of the half-cell on the right, the anode being written on the left
- CThe potential of the half-cell on the right hand side minus that of the half-cell on the left, the anode being written on the left
- DThe potential of the anode alone, since the cathode is taken as zero
Q3.The standard hydrogen electrode, written as Pt(s)|H2(g)|H+(aq), is assigned zero potential at all temperatures and is set up with:
- AHydrogen gas at any convenient pressure over a platinum electrode in one molar acid
- BHydrogen gas at one bar and hydrogen ion concentration of one molar, over a platinum electrode coated with platinum black
- CHydrogen gas at one atmosphere over a bare gold electrode in pure water
- DHydrogen ion concentration of one molar with no gas bubbled through
