You should use NO MORE THAN 100 mL 0.25 M NH4OH, 4 g Ca(NO3)2· 4H2O, and/or 3 g (NH4)2HPO4. NOTE: This is not a stoichiometric recipe. Part of the grading for this lab will be based on your ability to determine appropriate quantities of each reactant. Clearly show the actual amount of each reactant you intend to use. Determine the mass or volume of each reactant in the proper stoichiometric ratio, to synthesize and analyze a sample of calcium hydroxyapatite. The unbalanced equation for the reaction is: H3O+(aq) + Ca(NO3)2(s) + (NH4)2HPO4(s) + NH3(aq) --> Ca10(PO4)6(OH)2(s) + NH4NO3(aq)
