We’re being asked to determine the mass of platinum electroplated from a Pt(NO3)2 solution.
The electrolysis of the solution is done with a current of 0.500 A for 55.0 s.
The flow for this problem will be like this:
Duration of electrolysis (current applied) → Charge applied (Faraday’s constant) → Moles of electrons (mole-to-mole comparison) → Moles of metal (molar mass of Pt) → mass of metal
What mass of platinum could be plated on an electrode from the electrolysis of a Pt(NO3)2 solution with a current of 0.500 A for 55.0 s?
a) 27.8 mg
b) 45.5 mg
c) 53.6 mg
d) 91.0 mg
