Living next to a lake near volcanic activity can be deadly. There can be large amounts of CO₂ dissolved in the water. An earthquake, landslide, or even rapid cooling can trigger the release of the CO₂, causing death nearby. The water of the lake in these cases is A) an unsaturated solution. B) a saturated solution. C) a supersaturated solution. D) a completely unsaturated solution.

Question

The water of the lake is a supersaturated solution because it holds more dissolved COS (in this context, a placeholder for a gas, likely meant to represent CO2 or a similar gas) than it can under normal conditions, due to the high pressure and possibly lower temperature. When a disturbance occurs, the excess gas is released suddenly.
