Solvents and Solutions Concepts

The video tutorial introduces solution chemistry, focusing on aqueous systems. It explains the solvation process, differentiating between solutes and solvents. The tutorial discusses polar and nonpolar solvents, highlighting their ability to dissolve different compounds. It covers electrolytes, their role in conductivity, and the concept of hydrates. The video concludes with an exploration of suspensions, colloids, and emulsions, providing examples and characteristics of each type of mixture.

What is the term for the substance that gets dissolved in a solution?

• Solvent
