In which example is the solute a gas but the final solution a liquid?
Answer and explanation
Correct answer: Oxygen in water
Oxygen is a gas, so it acts as the gaseous solute. Water is a liquid and acts as the solvent. The broad physical category of a solution is named from the state of its solvent; therefore oxygen dissolved in water is a gas-in-liquid solution and its final form is liquid. Brass and zinc in copper are solid solutions, while camphor in nitrogen has a gaseous solvent.
