Finding the Mass of a Plated Metal
Not what you're looking for?
Calculate how many grams of gold would be plated out on a coin, if a current of 2.3 (Amp) is applied for 15 min to an electrolytic cell shown above.
The following reaction is occurring:
Au^3+ + 3 e- → Au
MW for gold equals 197g / mol.
1 amp (A) = 1 coulomb/second (C/s)
Charge on 1 mol of electrons = 96500 coulombs (C) = 1 faraday (F)
Calculate the number of grams plated out. You must take into consideration the number of moles of electrons necessary to reduce each gold ion to gold solid.
