alleryIn electroplating silver onto a spoon, the cathode is:
AThe electrolyte
BThe SPOON (object being plated)
CThe wire
DThe silver plate
Answer & Solution
Correct answer: B. The SPOON (object being plated)
In electroplating, the object to be plated is the cathode (reduction surface).
Silver ions from solution are reduced (Ag+ + e- → Ag) and deposit on the spoon.
A pure silver bar acts as anode (oxidation, replenishing Ag+ in solution).
