You have been instructed to make a silver film that is 0.2 to 0.4 mm thick. You make an electroplating from silver nitrate solution, and use a current of 1.5 A for 3.0 min to silver the surface. a) Is electroplating a galvanic or electrolytic process? b) What mass of silver is plated on the battery surface? c) How many silver atoms were deposited on the surface?
A casing for a button battery needs to be silver-plated. You have been instructed to make a silver film
that is 0.2 to 0.4 mm thick. You make an electroplating from silver nitrate solution, and use
a current of 1.5 A for 3.0 min to silver the surface.
a) Is electroplating a galvanic or electrolytic process?
b) What mass of silver is plated on the battery surface?
c) How many silver atoms were deposited on the surface?
d) Have you managed to make a silver film of suitable thickness? Your battery is a cylinder with
radius 3.0 mm and height 2.0 mm. You can assume that the silver coating is perfectly
even. Silver has a density of 10.49 g/cm3.
