In the method of electroplating on a vessel with zinc
- AThe vessel is made to be the negative pole.
- BPure zinc is made to the positive pole.
- CThe vessel is made negative pole and pure zinc as positive pole.
- DThe pot is made the positive pole and zinc the negative pole.
Show answer and explanation
Correct answer: (c) The vessel is made negative pole and pure zinc as positive pole.
Explanation
In electroplating, the object to be plated is the cathode (negative electrode) and the plating metal is the anode (positive electrode), in a solution of that metal's salt.
To zinc-plate a vessel, the vessel is the negative pole and pure zinc the positive pole. Zinc ions from the solution are deposited on the vessel, and the zinc anode dissolves to replace them.
