An iron nail was kept immersed in aluminum sulphate solution. Correct observation
made after half an hour, would be.
(a) the colorless solution changed to green.
(b) a grey coating was deposited on iron nail.
(c) the iron nail be4came red, the colorless solution remained colorless.
(d) the solution remained colorless and no deposition observed.
Dear Student,
The correct option is d) the solution remained colorless and no deposition observed.
No reaction will take place since aluminium is more reactive than iron and hence it prefers to stay in combined state with sulphate rather than separating from it.
