An electrolytic cell process involves plating Zr(s) from a solution containing Zr⁴⁺. If 5.80 amp is run through this mixture for 1.86 h, what mass of Zr is plated?

Question

Quizplus · Accepted Answer

To calculate the mass of Zr plated, use the formula: mass = (It/nF) * M, where I = current (5.80 A), t = time (1.86 h = 6696 s), n = number of electrons (4 for Zr^4+), F = Faraday's constant (96485 C/mol), and M = molar mass of Zr (91.22 g/mol). The calculation gives approximately 9.18 g.
