Depending upon the physical states of the solute and the solvent, the solutions can be classified into the following types:
|
Solute |
Solvent |

Out of these nine types of solutions, three solutions, namely solid in liquid, liquid in liquid, and gas in liquid are very common. In all these three types of solutions, liquid acts as a solvent.
The solutions in which water is the solvent are called aqueous solutions while those in which the solvent is other than water are called non-aqueous solutions. The common non-aqueous solvents are ether, benzene, carbon tetrachloride, etc.
What is camphor in N2 gas an example of?
Answer & explanation
Correct answer: option 3
The answer is 3. Solid in gas solution.
Camphor is a solid at room temperature, and nitrogen gas (N2) is a gas at room temperature. When camphor is dissolved in nitrogen gas, it forms a solid in gas solution. This is because the camphor molecules are dispersed throughout the nitrogen gas on a molecular level.
The other options are not correct. A solid in liquid solution is a solution of a solid in a liquid. A liquid in gas solution is a solution of a liquid in a gas. Gas in gas solution is a solution of two or more gases.
Therefore, camphor in N2 gas is an example of a solid in gas solution.
