If carbon dioxide is dissolved in water, what state is assigned to the solution?
Answer and explanation
Correct answer: Liquid
The governing concept is that the physical state assigned to an ordinary solution generally follows the state of its solvent. Carbon dioxide is the gaseous solute, but water is the liquid solvent and continuous medium. Therefore carbonated water is treated as a liquid solution. The presence of a gas as solute does not make the whole solution gaseous, and it certainly does not make it solid or plasma. Hence B is correct.
