What denotes an ideal-dilute solution?

• A. Only the solvent obeys Raoult's law
• B. The solute obeys Raoult's law
• C. The solute obeys Henry's law and the solvent obeys Raoult's law
• D. Both components obey Raoult's law

Answer: (C)

An ideal-dilute solution is characterized by specific behavior of its components, particularly when considering the laws governing their interactions. In such a solution, the solute tends to be present in relatively low concentrations, which allows us to apply certain laws more effectively. The correct understanding is that in an ideal-dilute solution, the solute behaves in accordance with Henry's law. This law states that the concentration of a gas in a liquid is proportional to the pressure of that gas above the liquid, which applies well when the solute is at low concentrations. Simultaneously, the solvent behaves according to Raoult's law, which indicates that the partial vapor pressure of each component in a solution is directly related to its mole fraction in the mixture. In this context, the combination of Henry's law for the solute and Raoult's law for the solvent accurately reflects the behavior of components in an ideal-dilute solution, thus making this choice the correct representation.
