Explanation:
In silver plating, the object to be plated (e.g., a spoon) is made from the cathode of an electrolytic cell. The anode is a bar of silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of silver cyanide, AgCN, in water.

Answer:
When electric current is passed through the solution, it splits up into silver ions (positive) and nitrate ions (negative). The silver ions in the water are attached to the negative (cathode) spoon and stick to it. the negative nitrate ions are attracted to the positive electrode, which is the bar of silver.
To make up for the loss of silver from the solution, silver form the anode goes into the solution. this goes on until the spoon is smoothly plated with silver. The silver bar is used in this process.
