Introduction to Solutions: What They Are and How They Form

The video discusses the concept of solutions and how they are formed by dissolving solutes into solvents. It covers definitions of terms such as solute, solvent, dilute, concentrated, and saturated solutions. The video also explains how different types of substances dissolve in different solvents and how state symbols in a reaction can determine whether a substance is in solution or in a solid state. The conservation of mass during the formation and evaporation of a solution is also discussed.
