This diagram shows the stability of ferrous iron minerals as a function of pH and sulfide for fixed total Fe and CO. 2. Mixtures. Solutions are a type of mixture, so to understand solutions, first we have to know what a mixture is…. A . mixture. is a combination of two or more substances. Each substance keeps it’s own properties, even though it is mixed with another substance. They . Dissolving a salt.... A salt is an ionic compound - usually a metal cation bonded to a non-metal anion.. The dissolving of a salt is an example of equilibrium.. The cations and anions are attracted to each other in the salt.. Introduction. Preformulation study is the foundation of developing robust formulation..
