How long did nickel plating take if a 1.8 g layer of nickel was deposited on the product at a current of 2 A?

How long did nickel plating take if a 1.8 g layer of nickel was deposited on the product at a current of 2 A? The electrochemical equivalent of nickel is 3 * 10 in the seventh degree min kg / C.

To determine the duration of nickel plating, we will use the first Faraday’s law: m = k * I * t, whence we express: t = m / (I * k).

Values of variables and constants: m is the mass of the deposited nickel layer (m = 1.8 g = 1.8 * 10 ^ -3 kg); I – current strength (I = 2 A); k – electrochemical equivalent of nickel (k = 3 * 10 ^ -7 kg / C).

Let’s make a calculation: t = m / (I * k) = 1.8 * 10 ^ -3 / (2 * 3 * 10 ^ -7) = 3000 s or 50 minutes.

Answer: Duration of nickel plating is 50 minutes.
