3. Then, the sulfate ions (negatively charged) will arrive to the
positively charged ions, and release electrons that move through the battery
towards the negative electrode.
2. When we turn the power on, the copper/sulfate solution splits
into ions. Copper ions (positively charged) are
attracted to the negatively charged electrode and slowly settle on it which causes
a layer of copper plate to appear.
1. We dip the two electrodes that we have into the solution and
connect them via a circuit. And so the copper becomes a positive electrode (anode)
and the sulfate becomes a negative electrode (cathode).
The Process is as follows:
But to do electroplating in these ages, you have to pick the right electrodes and electrolyte by knowing
about the chemical reactions that you want to happen when you turn on the
electric current. So if you want to copper plate something you need an
electrolyte made from a solution of a copper salt, however, for gold plating
you need a gold-based electrolyte—and so on.
When it was first discovered by Luigi, it used to work through using
the electrodeposition process for the electroplating of gold.
Electroplating is useful for coating a cheaper metal with a more
expensive one, such as copper or silver.

And to sort it in the order of
discoveries and evolvement :
has been discovered firstly in France,
then later on got licensed and accepted in England.
Richards Elkington used potassium cyanide as their
electrolyte and managed to create a feasible electroplating method for gold and
silver. He received a license for electroplating and his method became widely
spread throughout the world starting from England.
But later on, John Wright managed to use potassium cyanide as an electrolyte for
gold and silver, after he discovered that it is better and more efficient
Electroplating was first discovered by Luigi
Brugnatelli through using the electrodeposition process for the
electroplating of gold. However, he was disregarded by the French Academy of
