The corresponding equilibrium constant expression for this system is: [Ag+]2 [SO42 ] K = -----[Ag2SO4] Since the solid component has a near-constant concentration, it is not used in the equilibrium expression, simplifying it to the . solubility product: K = [Ag+]2 [SO42 ] The new symbol . Ksp. is called the . solubility product constant

Sep 03, 2015 · The standard solution has a known FeSCN2+ concentration. Figure 1. To prepare the standard solution, a very large concentration of Fe3+ will be added to a small initial concentration of SCN– (hereafter referred to as [SCN–]i. The [Fe3+] in the standard solution is 100 times larger than [Fe3+] in the equilibrium mixtures.
