Why d electrolyte must contain metal ions of anode?
Thanx for sharing~

[Patrick Chai Teck Khiong]

because it need to be electroplated of that metal..

[Ling Teck Ping]

not using d electrolyte contain d metal ions same as anode,d anode metal ions won't selected to be discharge at the cathode??

[Patrick Chai Teck Khiong]

Anode is the plating metal and the electrolyte must contain the metal ion of the plating metal. At the cathode, the metal ion from the electrolyte will be discharged and plate the cathode.

[Leh Siong Lu]

In my opinion, if we use electrolyte contain the others metals ions other than anode, reaction between the metal ions and electrolyte will occur due to the different in electropositivity (such as displacement). It will influence the product at cathode since the positions of these ions in electrochemical series will influence the ions choosen to be discharged at cathoe.

[Sia Pik Chan]

using acid also can right? other than the electrolyte which contain the metal ion.
