Question

Questions 1 & 2 refer to the solubility of iron(II) phosphate, Fe3(PO4)2: Fe3(PO4)(s) = 3Fe2(aq) + 2PO4 (aq) 1. The Kp for Fez(PO4)() is 1.0 x 10" at 25°C. What is the solubility of Fe (PO4)2 in mol L '? a) 2.5 x 108 b)3.1 10° C)6.3 x 10* d) 1.0 x 102 €) 4.0 x 10 2. If 25.0 mL of 2.0 x 10' M FeSO, is added to 25.0 mL of a solution of 1.0 x 10-MK PO4, which statement is correct? a) The ionic product is 8.0 x 10 and Fe:(PO)(s) precipitates. b) The ionic product is 2.5 x 10 and Fe:(PO.),(s) precipitates. c) The ionic product is 8.0 x 10's and Fe:(PO)(s) does not precipitate. d) The ionic product is 2.5 x 10 " and Fe:(PO4h(s) does not precipitate. e) none of the above

Hi. can some one please explain me the solution for question 2. the correct answer is B. thanks.

Answer 1

fez(poyla 3 Fe2+ + 2poy? (s) com sp=) x1036 1 we know that ionic product is the product of concentration of ion is given temperature at any solution is called Skip But kep is oorly at saturated solution. - whose value is equal to product of concentration of los if kir y ksp then saturation takes polene. from the above chemical rexos, - kip : (Peer j3 (page 2 New concentration of tele after mixing M.U = maua Total volume after mining o arros* RO= *310-5 m Hew concentration of pays I miwia mava 1 1010x air > * To *.2 05 X10-'0 m Kipa (feat) (roy3) • (0533 (0:5X 1070j?. 2.5 X30-36
