AP Inter Chemistry 2 Marks Important Questions 2025

The important AP Inter 2nd Year Chemistry 2 Marks Questions 2025 are listed below with solutions.

1. Define The Term Solution?
   Answer: A solution is a homogeneous mixture of two or more substances, where the solute is uniformly distributed in the solvent.
   Example: Sugar dissolved in water (Sugar = solute, Water = solvent) Saltwater (Salt = solute, Water = solvent)
   
   
2. Define Molarity
   Answer: Molarity is the number of moles of solute present in 1 litre (1000 mL) of solution.
   
   
3. Calculate the molarity of the solution containing 5g of NaOH in 450ml of a solution.
   Answer: 0.27
   
   
4. Define mole fraction
   Answer: The ratio of several moles of one component of the solution to the total number of moles of all the components of the solution is called mole fraction.
   
   
5. Define molality
   Answer: The number of moles of solute present in one kilogram of solvent is called molality.
   
   
6. State Raoult’s law
   Answer: Raoult’s law for volatile solute: For a solution of volatile liquids, the partial vapour pressure of each component of the solution is directly proportional to its mole fraction present in the solution.
   Raoults law for non-válatlle solute: The relative lowering of the vapour pressure of a dilute solution containing non-volatile solute is equal to the mole fraction of solute.
   
   
7. State Henrýs law.
   Answer: At constant temperature, the solubility of a gas in a liquid -is directly proportional to the partial pressure of the gas present above the surface of the liquid. The partial pressure of the gas in the vapour phase is proportional to the mole fraction of the gas in the solution.
   
   
8. What is the Ebullioscopic constant?
   Answer: The elevation of boiling point observed in one molal solution containing non-volatile solute is called the Ebullioscopic constant (or) molal elevation constant.
   
   
9. What are isotonic solutions?
   Answer: Solutions having the same osmotic pressure at a given temperature are called isotonic solutions.
   
   
10. What is a Cryoscopic constant?
    Answer: The depression in the freezing point observed in one molal solution containing a non-volatile solute is called the cryoscopic constant (or) molal depression constant.
