1.	If a metal is to be electroplated with silver, what would happen if a solution of silver nitrate alone is used as an electrolyte ? What is the preferable electrolyte and why is it used ?
Answer» Solution :(i) Purpose of silver plating (ii) Solubility of silver nitrate (iii) Quantity of ions present in the electrolyte. (iv) RELATION between the quantity of ions present in the electrolyte and the quality of coating. (v) Soluble salt of silver that can form a COMPLEX with NaCN. (VI) IOns produced from the complex (VII) Change in the concentration of ions due to the complex formation. (viii) Effect of change in concentration of ions on quality of plating.
