As temperature rises, solids generally become more soluble in water, but gases become less soluble. If a soft drink contains high concentrations of sugar and carbon dioxide, which of the following may be expected to happen if it is cooled down?
- Sugar may precipitate out.
- Gas bubbles may form and produce foam.
- Water may evaporate rapidly.
The sugar becomes less soluble, and may come out of solution as a solid. The gas becomes more soluble and will remain in solution. If anything. the water will evaporate more slowly at lower temperatures.
