Is there any method to make sure a electroplated layer of iron oxidizes into magnetite (Fe3O4) instead of hematite (Fe2O3)?
I am currently electroplating iron on copper using a DIY setup in my lab. Steel sheet as anode with electrolyte having 5% acetic acid with sodium carbonate to form sodium acetate and added some NaCl ...

Electrolysis when E_cell = 0
I'm a bit confused by the electroplating of Zinc onto Copper, with Zinc (anode) and Copper (cathode) electrodes in a Zn(NO3)2 solution.
The reduction reaction is: Zn2+ + 2e- ---> Zn (s) (E_rxn = -0....

What is a suitable material for a cathode in electroplating experiment?
I am going to do an electroplating experiment, whereby I will be using a Cu(NO3)2 solution to plate onto a cathode.
What is an easily accessible cathode which I can use for this? Would a strip of Ag (...

How is it possible to electroplate using an Al3+ solution, when water is a stronger oxidant?
Suppose that I wanted to electroplate Al(s) onto a Cu(s) Cathode, (using an Aluminium Nitrate solution and Al(s) anode).
At standard conditions, Al(s) is the strongest reducing agent, which is good. ...

Electrolytic cell to remove soft solder from silver?
Hi my chemistry is pretty dire but have vague idea that an electrochemical cell could be used to remove soft solder (lead/tin probably) from a piece of sterling silver in need of a repair.
The ...

Why can higher voltages lead to less efficient electroplating?
I was reading up on electroplating and I came across some things which really confused me:
Faraday's First Law says that the amount of metal plated onto the cathode is proportionate to the current, ...
