The correct Answer is A-3, B-1, C-2, D-4
Explanation
Solutions are homogeneous mixtures of two or more components. The component present in the largest quantity is known as the solvent, and the other component(s) present in smaller quantities are called the solute(s). Solutions can exist in various physical states depending on the physical state of the solute and the solvent.
Statement-wise Analysis
- A. Liquid in liquid: This type of solution involves a liquid solute dissolved in a liquid solvent.
- Correct Match: 3. Ethanol dissolved in water. Ethanol (liquid) dissolves in water (liquid) to form a homogeneous solution.
- B. Gas in solid: This type of solution involves a gas solute dissolved in a solid solvent.
- Correct Match: 1. Solution of hydrogen in palladium. Hydrogen gas can be adsorbed and absorbed into the lattice of palladium metal, forming a solid solution.
- C. Gas in liquid: This type of solution involves a gas solute dissolved in a liquid solvent.
- Correct Match: 2. Aerated drinks (oxygen in water). Aerated drinks contain carbon dioxide gas dissolved under pressure in water. Oxygen also dissolves in water.
- D. Solid in liquid: This type of solution involves a solid solute dissolved in a liquid solvent.
- Correct Match: 4. Glucose dissolved in water. Glucose (solid) dissolves in water (liquid) to form a homogeneous solution.
Key Takeaway
The classification of solutions is based on the physical states of the solute and the solvent, determining the type of solution formed.
