Dissolving oxygen in water is related to which type of solution?
Answer and explanation
Correct answer: Gas in liquid solution
Oxygen exists as a gas, whereas water is a liquid. When oxygen dissolves in water, oxygen is the gaseous solute and water is the liquid solvent. Hence the mixture is a gas-in-liquid solution. This dissolved oxygen supports aquatic organisms, but that biological importance does not change the classification. The other choices have incorrect state combinations.
