Water found in the pores of a soil has the following properties: Negligible ionic strength (activity = concentration) a constant pH of {pH} (Ca2+) = 10{Ca} M total P = 10{P} M Given the dissolution reaction of brushite is written: CaHPO4·2H2O(s) + H+ (aq) ⇄ Ca2+(aq) + H2PO4– (aq) + 2H2O …and that H3PO4 has a pKa2 of 7.21, calculate log(IAP) (same as log(Q)) of the reaction, and save your answer for the next question.
