Chemical Equilibrium: Simultaneous Equilibria

This lecture covers the concept of simultaneous equilibria in chemical systems, focusing on the calculation of equilibrium constants and concentrations of ions in saturated solutions. Examples include the dissolution of magnesium fluoride and strontium fluoride, as well as the solubility of lead sulfate and silver sulfate. The instructor explains the methodology for solving such equilibrium problems, emphasizing the importance of identifying species, determining unknowns, and setting up a system of equations based on equilibrium constants and charge balance.
