Calculate the molar concentration of ferrocyanide in a, Ask an Expert

Academics

A. Calculate the solubility (milligrams per liter) of Zn2Fe(CN)6, which dissociates as follows with Ksp = 2.1E10-16.

Zn2Fe(CN)6(s) --> 2 Zn2+ + Fe(CN)64- (Ferrocyanide)

B. Calculate the molar concentration of ferrocyanide in a solution of 0.031 M ZnSO4 saturated with Zn2Fe(CN)6. ZnSO4 will be completely dissociated into Zn2+ and SO42-

C. What molar concentration of K4Fe(CN)6 should be added to a suspension of solid Zn2Fe(CN)6 in water to give [Zn2+] = 6.9 10-7 M?
