Solutes Solvents Solutions The Science of Dissolving

The video tutorial introduces the concepts of solute, solvent, and solution, explaining how solids dissolve in liquids. It distinguishes between soluble and insoluble substances, providing examples like salt and sugar for soluble, and sand and stone for insoluble. The video describes methods to separate soluble substances, such as evaporation, and techniques for separating insoluble substances, including sedimentation, decantation, and filtration. It concludes with a summary and encourages viewers to explore additional resources.
