Q: Which component is present in a smaller amount in a binary solution?

Answer: B. Solute — In a binary solution, the substance present in a smaller quantity is called the solute.

Q: What is the universal solvent?

Answer: C. Water — Water is known as the universal solvent because it dissolves a wide range of substances.

Q: Which factor does NOT affect the solubility of a solid solute in a liquid?

Answer: D. Atmospheric pressure — The solubility of solids in liquids is generally unaffected by changes in pressure.

Q: Consider a saturated solution at 25°C. If the temperature is increased to 50°C, the solution becomes:

Answer: B. Unsaturated — Since solubility typically increases with temperature, a saturated solution becomes unsaturated when heated.

Q: A substance 'X' loses its water of crystallization upon exposure to air and turns into a powdery form. This process is called:

Answer: B. Efflorescence — Efflorescence is the property of certain hydrated salts to lose their water of crystallization to the atmosphere.
