Question
How many coulomb of electricity would be required to reduce the iron in 32.9 g of potassium hexa cyano ferrate (III) K3Fe(CN)6 to metallic iron ?
(at mass of K = 39, Fe = 56)
(at mass of K = 39, Fe = 56)
Options
A.289500 C
B.28950 C
C.9650 C
D.19300 C
Solution
Iron in the complex is Fe3+
K3Fe(CN)6 + 3e- → 3K+ 6CN- + Fe
1 mol 3 F
= 0.1 mol 0.3 F
K3Fe(CN)6 + 3e- → 3K+ 6CN- + Fe
1 mol 3 F
= 0.1 mol 0.3 FCreate a free account to view solution
