For ionic compounds with limited solubility in water, an equilibrium constant, Ksp, can be defined from the ion concentration in water from the equation: where MmAn is the slightly soluble substance and Mn+ and Am- are the ions produced in solution by dissosiation of MmAn. Comparing Q and Ksp enables us to determine whether a precipitate will form when solutions of two soluble salts are mixed. Why does an iodine deficiency cause a goiter?

Ca(NO 3 ) 2 sample. H2O] is a sparingly soluble salt that is the other major component of kidney stones [along with Ca3(PO4)2]. When trying to write the equation for #K_(sp)#, you need to know how to break the compound into ions (identify the monoatomic and polyatomic ions), how many moles of each ion are formed, and the charge on each ion. Convert the solubility of the salt to moles per liter. The solubility product expression is as follows: B To solve this problem, we must first calculate the ion productQ = [Ba2+][SO42]using the concentrations of the ions that are present after the solutions are mixed and before any reaction occurs. Its solubility in water at 25C is 7.36 104 g/100 mL. Sulfuric acid reacts with calcium carbonate to form calcium sulfate, carbon dioxide and water. An interesting example of this occurs in nature. The product of solubilities of the ions with the number of each ion in power is known as the solubility product. Will a precipitate form when we micx Ca(NO3)2(aq) with NaOH(aq) if the concentrations after mixing are both 0.0175M?
