Understanding Dissolving and Solutions

This video tutorial explains the process of dissolving, where solid particles mix with liquid particles to form a solution. It introduces key terms such as solute, the substance that dissolves, and solvent, the substance that dissolves the solute. The solvent is present in a larger amount and determines the state of the solution. The video also covers how liquids can dissolve and diffuse solids, using potassium permanganate as an example. The tutorial concludes with a recap of the dissolving process and the roles of solute and solvent.
