Using electrolysis to put a thin layer of metal on an object
1 of 8
Why is electroplating done?
-to make the object look more attractive -to protect a metal object from corroding -to increase the hardness of the surface -to reduce costs by using a thin layer of metal instead of the pure metal
2 of 8
In electroplating what is used as the negative electrode?
The object going to be plated
3 of 8
In electroplating what is the positive electrode made from?
The plating metal
4 of 8
What is the electrolyte used in electroplating?
A solution containing ions of the plating metal
5 of 8
In electroplating, unlike electrolysis, the positive electrode is not .........?
Inert, it produces ions of the metal used to plate the object
6 of 8
What is the half equation at the positive electrode?
Ni (s) --> Ni2+ (aq) + 2e-
7 of 8
What is the half equation at the negative electrode?
