Bismuth can be electrolytically reduced according to the following reaction:

BiO(+)+ 2H(+)+ 3e¯ >>> Bi + H2O

How many grams of bismuth can be reduced by applying a 5.60 A current for 23.8 min. to a solution containing BiO+
ions
(assuming 100% efficiency)?

1 answer

96,485 Coulombs can plate out approx 209/3 grams Bi. You need a better answer than that estimate.

How many coulombs do you have? That's
C = amperes x seconds = approx 5.60 x 23.8 x 60 s/min = ?
209/3 x ?coulombs/96,485 = g plated out.
