What usually happens when extra solute is added to a saturated solution at the same temperature?
Answer and explanation
Correct answer: Extra solute does not dissolve
At a fixed temperature, a saturated solution already contains the maximum equilibrium amount of dissolved solute. Adding more solute therefore generally leaves the excess as an undissolved solid, unless a condition such as temperature or solvent amount changes. Thus A is correct; boiling, disappearance of solvent, and zero pressure do not follow.
