11.1: The Dissolution Process
Air is a gaseous solution, a homogeneous mixture of nitrogen, oxygen, and several other gases. Oxygen (a gas), alcohol (a liquid), and sugar (a solid) all dissolve in water (a liquid) to form liquid solutions. Table 11.1.1 11.1. 1 gives examples of several different solutions and the phases of the solutes and solvents.
