Carbonate Equilibrium: Equilibrium Concentrations and pH Calculations

This lecture by the instructor covers the carbonate system, focusing on open and closed systems, equilibrium equations, and concentrations in pure systems. It delves into the equilibrium pH calculations, proton balance, and the impact of adding acids. The lecture also explores the dissolution of CaCO3 in open systems, equilibrium constants, and the relationship between HCO3- and Ca2+ in rivers. Practical exercises are provided to apply the theoretical concepts discussed.
