These tasks: t (electrolysis duration) = 10 min (in SI t = 600 s); m (mass of nickel obtained) = 0.3 g (in SI system m = 0.3 * 10 ^ -3 kg).
Constants: k (electrochemical equivalent of nickel) = 30.4 * 10 ^ -8 kg / C.
The current strength during nickel electrolysis is determined using the first Faraday’s law: m = k * I * t, whence I = m / (k * t).
Let’s make a calculation: I = 0.3 * 10 ^ -3 / (30.4 * 10 ^ -8 * 600) = 1.64 A.
Answer: During nickel electrolysis, the current was 1.64 A.
