Iron molybdate solubility
WebFor ionic compounds with limited solubility in water, an equilibrium constant, Ksp, can be defined from the ion concentration in water from the equation: MmAn(s) = mMn+(aq) + nAm-(aq) where M m A n is the slightly soluble substance and M n+ and A m- are the ions produced in solution by dissosiation of M m A n. Ksp = [Mn+]m * [Am-]n WebNormal iron molybdate (monomolybdate) was thought to be the main product of the exchange reac tion (1) between ammonium molybdate and iron(III) nitrate. Its formation …
