WebAir 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 gives examples of several different solutions and the phases of the solutes and solvents. WebJan 20, 2024 · Let's consider the general equation X − Y X ( s) → X X + X ( a q) + Y X − X ( a q) with a Δ H = C. Intuitively, if the reaction is endothermic ( Δ H > 0 ), an increase in temperature should help the dissolution (more heat to be absorbed by the salt while dissolving). You can rationalize this further using the Le Châtelier's principle:
