What term describes the amount of a substance required to form a saturated solution with a given amount of solvent at a specific temperature?

• A. Solubility
• B. Hydration
• C. Anhydrous
• D. Immiscible

Answer: (A)

Solubility is the maximum amount of a solute that can dissolve in a given amount of solvent at a specified temperature, forming a saturated solution. This exactly matches the idea in the question: it describes the quantity of substance needed to reach saturation in the solvent at that temperature. Once that limit is reached, any extra solute won’t dissolve and will precipitate out. Hydration is about the solvent molecules surrounding dissolved particles, not the quantitative limit. Anhydrous means lacking water, which isn’t about solubility. Immiscible refers to liquids that do not mix to form a single phase, not to the amount that can dissolve.
