Answer to Question #111808 in Inorganic Chemistry for Sanwal Nasir Gill

Question

You have a 50mL solution of Iron (1l) Sulfate of 1M concentration. Assume the temperature is 298 K. Do not forget to write reaction formulas. (E) a) Describe what happens if you put a copper tube in the solution. b) Describe what happens if you put a piece of zinc plate in the solution.

Answer 1

Solution.

a)

If we put a copper tube in a solution of iron sulfate (2), the reaction will not occur, since the electrode potential of copper is greater than that of iron.

b)

If we put a zinc plate in a solution of iron sulfate (2), the reaction will go with the formation of a layer of iron on the zinc plate and the formation of zinc sulfate. Since the electrode potential of zinc is less than that of iron.

$FeSO4 + Zn = Fe + ZnSO4$

Answer:

a)

-

b)

$FeSO4 + Zn = Fe + ZnSO4$
