Put the aluminum wire into the ferrous sulfate solution. What color changes on the surface of the aluminum wire?
The aluminum wire is dark and has no special color change and won't get the metal iron, because the iron reacts with the acid!
There would be no reaction if there were no wires. Because the aluminum sheet has a dense oxide film.Aluminum oxide does not react with ferrous sulfate.If it's ideal. Think aluminum wire is pure aluminum: the aluminum wire into the ferrous sulfate solution, there are bubbles generated, the gas is hydrogen
Reason: ferric chloride hydrolysis is acidic, and hydrogen ions in solution react with metal aluminum
The aluminum wire is put into the solution of ferrous sulfate. The bubbles are produced and the gas is hydrogen
