NCERT Class 12 Chemistry Chapter 1 Solutions Test Mock Test
This free online test covers Chapter 1, Solutions, 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 solution of hydrogen in palladium is given in the chapter as an example of:
- AA liquid solute dissolved in a solid solvent
- BA gaseous solute dissolved in a solid solvent
- CA solid solute dissolved in a gaseous solvent
- DA gaseous solute dissolved in a liquid solvent
Q2.Which of these ways of expressing concentration changes with temperature?
- AMole fraction, because it is a ratio of numbers of moles
- BMolarity, because it is defined per litre of solution and volume varies with temperature
- CMass percentage, because it is a ratio of masses
- DMolality, because it is defined per kilogram of solvent
Q3.A solution in dynamic equilibrium with undissolved solute, in which no more solute can be dissolved at that temperature and pressure, is called:
- AAn ideal solution, one that obeys Raoult's law at all concentrations
- BAn unsaturated solution, and the concentration of solute in it is the solubility
- CA supersaturated solution, whose concentration exceeds the solubility
- DA saturated solution, and the concentration of solute in it is the solubility
