Question

if I introduce Zn into a solution of FeSO4 what is the appearance of the metal at the end of the experiment? And what is the color of the solution at the end of the experiment? Thanks

Answer 1

Answer:

here is your answer

Explanation:

Zinc sulphate: Colorless

Ferrous sulphate: Light green

Copper sulphate: Blue

Aluminium sulphate: colorless

When Al is added to ferrous sulphate solution:

2Al + 3FeSO4 -> Al2(SO4)3 + 3Fe

Green color of the solution disappears

When Al is added to copper sulphate solution:

2Al(s) + 3CuSO4(aq) -> Al2(SO4)3(aq) + 3Cu(s)

The green color of the solution becomes transparent

Answer 2

Explanation:

zinc sulphate colorless

ferrous sulphate light green

copper sulphate blue

aluminum sulphate colourless
