How do solid solutions and gas solutions form?

Answer 1

Solid solutions form when different solid materials are mixed at the atomic or molecular level, resulting in a homogeneous phase where the solute atoms or molecules occupy the lattice positions of the solvent material. This typically occurs when the solute and solvent have similar atomic sizes and crystal structures. Gas solutions arise when gases mix uniformly, often due to random molecular motion, allowing gas molecules to disperse throughout the volume of another gas. Both types of solutions rely on the principles of thermodynamics and molecular interactions to achieve stability and uniformity.
