How many grams of nickel would be electroplated by passing a constant current of 7.2 A through a solution of NiSO₄ for 90.0 min

Question

Quizplus · Accepted Answer

To find the mass of nickel electroplated, use the formula: mass = (It/nF) * M, where I is the current (7.2 A), t is the time in seconds (90.0 min = 5400 s), n is the number of electrons transferred per nickel ion (2 for Ni^2+), F is Faraday's constant (96485 C/mol), and M is the molar mass of nickel (58.69 g/mol). Calculating gives approximately 12 g.
