Explain the electroplating process of an iron key with silver. the materials provided for electroplating is AgNO3 solution, silver rod and iron key.

See explanation

Explanation:

The process of electroplating an iron key with silver involves electrolysis.

The anode is a silver rod, the electrolyte is AgNO3 solution while the cathode is the iron key. A battery is connected to provide energy to drive the non-spontaneous electrochemical reaction.

Electrons flow from the anode to the cathode. Silver ions from the silver rod replenishes the silver that is deposited on the iron key in order to continue the electrolytic process.

The silver anode is therefore depleted in mass while the iron key increases in mass.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
