Question

Select each side of the mass balance equation for an Fe 3 ( PO 4 ) 2 Fe3(PO4)2 solution where the species in solution are Fe 2+ Fe2+ , PO 3− 4 PO43− , HPO 2− 4 HPO42− , H 2 PO − 4 H2PO4− , H 3 PO 4 H3PO4 , and FeOH + FeOH+ . Identify the side of the mass balance equation that contains the iron-containing species. 3([ Fe 2+ ]+[ FeOH + ]) 3([Fe2+]+[FeOH+]) [ Fe 2+ ]+[ FeOH + ] [Fe2+]+[FeOH+] 2[ Fe 2+ ]+[ FeOH + ] 2[Fe2+]+[FeOH+] 2([ Fe 2+ ]+[ FeOH + ]) 2([Fe2+]+[FeOH+]) Identify the side of the mass balance equation that contains the phosphate-containing species. 3([ PO 3− 4 ]+[ HPO 2− 4 ]+[ H 2 PO − 4 ]+[ H 3 PO 4 ]) 3([PO43−]+[HPO42−]+[H2PO4−]+[H3PO4]) 3[ PO 3− 4 ]+2[ HPO 2− 4 ]+[ H 2 PO − 4 ] 3[PO43−]+2[HPO42−]+[H2PO4−] 2([ PO 3− 4 ]+[ HPO 2− 4 ]+[ H 2 PO − 4 ]+[ H 3 PO 4 ]) 2([PO43−]+[HPO42−]+[H2PO4−]+[H3PO4]) [ PO 3− 4 ]+[ HPO 2− 4 ]+[ H 2 PO − 4 ]+[ H 3 PO 4
