In this “Do-The-Review” episode, co-hosts John and Tracy Suchocki review the four main types of molecular interactions. This includes the dipole-dipole interaction as well as the ion-dipole, dipole-induced dipole, and induced dipole-induced dipole interactions. This is followed by a discussion of the many terms associated with solutions, such as solute, solvent, solubility, concentration, and the mole. The episode concludes with a discussion of reverse osmosis. Duration: 1:01.
