One of the qualitative differences between a real MO calculation and our scrap-paper approach is that mixing does occur between different kinds of orbitals. However, restrictions still apply.

Forces such as Cohesive as well as Adhesive forces still apply to mixtures; however, more importantly we focus on the interaction between different molecules. Why is oil only soluble in benzene and not water? Why do only "like" molecules dissolve in "like" molecules?

It discusses azeotropes, eutectics, and the impact of pressure on boiling points, emphasizing that lower pressures can lead to early boiling of mixtures. As temperature increases, mutual solubility improves until reaching the eutectic point, where distinct boiling behaviors occur.

It emphasizes the importance of using a volumetric flask for accurate measurements, detailing the steps of weighing the solute, dissolving it, and adding water to reach the desired volume before mixing thoroughly.

We start with the entropy of mixing and, for simplicity, restrain the discussion to binary mixtures.
