So these guys are at the maximum. Now, whenever we talk about normal equations or normal reactions, not fluidation reactions, we talk about equilibrium constants. In the same way, when we talk about salvation reactions, we could talk about something called solubility product constant or KST. Now, when we determine the normal equilibrium constant, we don't include solids and liquids in our calculation. And in the same way, when we talk about salvation or solubility product constant KFC, we don't include solids and liquids. For example, let's take a reaction of solid Orion compound AB that associates in water into A plus B.
