Which example shows solubility of a gas in a liquid?
Answer and explanation
Correct answer: Oxygen dissolved in water
Oxygen is a gas and water is a liquid, so oxygen dissolved in water is a gas-in-liquid solution. This dissolved oxygen supports aquatic respiration. Sand in water and a pebble in oil are examples of insoluble solids, while dust in air is a solid dispersed in a gas and is not a true molecular solution. The physical states identify the correct example.
