Metal Solubility: Processes and Equilibria

This lecture covers the processes of solid precipitation and dissolution of metals in the atmosphere, biomass assimilation, and water. It discusses the composition of natural waters, weathering, and the role of biological processes. The solubility of metal sulfides, hydroxides, and halides is explored, along with factors influencing solubility. The lecture also delves into the quantitative description of heterogeneous equilibria and the interactive polls on turning point. Various equilibrium constants and their relation to pH are analyzed, focusing on the distribution of iron species. The session concludes with exercises on estimating solubility products and the speciation of silver chloride in ammonia-containing solutions.
