FAQs on Past Year Paper - Solutions, Chemistry (Set - 3), Delhi, 2016, Class 12, Chemistry - Additional Study Material for Class 12

1. What are the solutions in chemistry?
Ans. In chemistry, a solution refers to a homogeneous mixture of two or more substances, where the solute is evenly distributed within the solvent. The solute is the substance being dissolved, while the solvent is the substance in which the solute is dissolved.
2. How can solutions be classified?
Ans. Solutions can be classified based on the state of the solute and solvent. If both the solute and solvent are in the same state (e.g., both are in a liquid state), then it is called a homogeneous solution. If the solute and solvent are in different states (e.g., gas dissolved in a liquid), then it is called a heterogeneous solution.
3. What is the difference between a solute and a solvent?
Ans. The solute refers to the substance being dissolved in a solution, whereas the solvent refers to the substance in which the solute is dissolved. The solute is present in a smaller amount, while the solvent is present in a larger amount.
4. How is the concentration of a solution measured?
Ans. The concentration of a solution can be measured in various ways, including molarity (moles of solute per liter of solution), molality (moles of solute per kilogram of solvent), and mass percent (mass of solute divided by mass of solution, multiplied by 100).
5. Can solutions be separated back into their original components?
Ans. Yes, solutions can be separated back into their original components through various methods such as evaporation, distillation, filtration, or precipitation. These methods help to recover the solute or solvent from the solution.
