A teapot with a surface area of 700 cm2 is to be silver plated. It is attached to the negative electrode of an electrolytic cell containing silver nitrate (Ag, + NO3 -). If the cell is powered by a 12.0-V battery and has a resistance of 1.80, how long does it take for a 0.133-mm layer of silver to build up on the teapot? (The density of silver is 10.5 x 103 kg/m3.) |
