The solubility product

(K_(sp))

for the second reaction is

10^(-26.4)M^(2)

. What molar concentration of

Fe^(3+)

would be needed to maintain the phosphate concentration below the regulatory limit of

1mg

P/L? For purposes of this problem, assume that equilibrium between

FePO_(4(s))

and its constituent ions has been achieved.
