Determine the silvering time of the part in a current of 10 A if 6.72 g of the substance is released.

These tasks: I (current strength when silvering the part) = 10 A; m (mass of released silver) = 6.72 g (in SI m = 6.72 * 10-3 kg).

Reference values: k (electrochemical equivalent of silver) = 111.8 * 10-8 kg / C.

The duration of the silver plating of the part can be determined using the first Faraday’s law: m = k * I * t, whence t = m / (k * I).

Let’s perform the calculation: t = 6.72 * 10-3 / (111.8 * 10-8 * 10) = 601 s.

Answer: The duration of the silvering of the part is 601 seconds.
