How is electroplating done?

A. A precipitation reaction is used to plate the cathode with an ion.
B. The metals in the anode and cathode electrodes trade positions.
C. Ions of one metal are reduced onto a cathode made of a different metal.
D. The anode is replaced by the object to be electroplated.
I think its D..?

The surfaces of the objects have to change

aaronq · Answer

In electroplating an ion is reduced onto a surface...so knowing that it's an electrochemical cell, where does reduction occur?

anonymous · Answer

oxidation occurs at the anode and reduction occurs at the cathode

aaronq · Answer

So, which one of the options looks like the correct answer?

anonymous · Answer

its A

aaronq · Answer

it's not A

anonymous · Answer

It'd B. Can't be A. because of the anode and cathode

aaronq · Answer

It's C.

anonymous · Answer

wait what... I'm so confused. i don't understand any of this electrochemistry

aaronq · Answer

it can be a bit confusing. This is a mental picture of how it works|dw:1407536483884:dw||dw:1407536604609:dw|
