Ag+ + 1e- → Ag(s)
• current = 2.00 A
• time = 2.30 min (convert to from min to s)
• Faraday’s constant = 96485 C/(mol e-)
• From the reaction: 1 mol e- produces 1 mol Ag(s)
It took 2.30 min using a current of 2.00 A to plate out all the silver from 0.250 L of a solution containing Ag +. What was the original concentration of Ag + in the solution?
