Now, initially, when we add photos chloride into water, the forward rate is much higher than the reverse rate. Eventually, however, though dynamic equilibrium is achieved, at this point, the forward rate is equal to the reverse rate. And at this point, the solution is said to be saturated, which basically means that the concentration of the ions or dissolved ions is that it's maximum. 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.
