Solubility and Solvent Properties

The video tutorial covers the concepts of polarity and solubility, explaining how solutes and solvents interact. It discusses the definitions of solute and solvent, and provides examples of soluble and insoluble substances. The tutorial also explains how solubility can be used to predict bond types, emphasizing the rule 'like dissolves like'. Common solvents like water and hexane are discussed, highlighting their roles in dissolving polar and non-polar substances respectively.

What is the term for the substance that dissolves in a solvent?

• Solvent

• Mixture

• Dissolved

Why do oil and water not mix?

• Both are polar
