Please pleaseee help me! I do not understand electrode potential well and exam is in a week :cry:
qn no. 1 (c)i - why is the polarity that way? Isn't the anode supposed to be the object to be plated since reduction takes place at the anode and therefore, it will gain the electrons from copper?
please help me understand it
At cathode always reduction takes place
At the anode always oxidation takes place
So the object to be plated is at the cathode & it will gain the electrons from copper
You can remember it this way if it helps:
CCR- Cathode cation reduction & RIG- reduction is gain
AAO- Anode anion oxidation & OIL- oxidation is loss
