Study Notes

A solution is a homogeneous mixture of two or more substances in one phase.
Solvent is a component of a solution.
Saturated solutions have the maximum dissolved mass of a substance at a given temperature.
Supersaturated solutions have more dissolved substances than possible and are unstable.
The formation enthalpy of a solution determines whether the solution process is exothermic or endothermic.
Liquid-liquid mixtures can be miscible or immiscible.
Like dissolves like applies to liquid-liquid and solid-liquid mixtures.
Adding a solid to a solvent changes the solvent's properties, known as colligative properties.
Colligative properties depend on the number of dissolved particles relative to the solvent particles.
An ideal solution's properties only depend on the solution concentration.
