Calculate pH of saturated solution of dicalcium phosphate (CaHP04) in water if its solubility is 3.16X10 -4 m. CaHPO4 (aq) Ca2+ (aq) + HP02- (aq) Although phosphoric acid is a triprotic acid, consider only pK Will not contribute to this dissociation: H2PO;(aq)+ plusminus H+(aq) + HPO;~(aq) pKa' =6.8 Assume that: CaHP04 is a strong electrolyte; Ionic strength of CaHP04 in water is negligible due to low concentration (alpha 1 for all ions). How much solubility of CaHP04 will change when l.OxlO"3 m MgCI2 is added to the same saturated solution of dicalcium phosphate? Assume that: MgCI2 is a strong electrolyte and very soluble in water; Ionic strength cannot be ignored; Precision of a single iteration, whenever necessary, is sufficient;
