Question: In a process called flash electroplating, a current of 2.50 10 3 A passes through an electrolytic cell for 5.00 minutes. How many moles

In a process called flash electroplating, a current of 2.50 × 10³ A passes through an electrolytic cell for 5.00 minutes. How many moles of electrons are driven through the cell?

Strategy

Because we know both the current and the time for which it was applied, we can use the relationship between charge and current in Equation 13.8 to obtain the charge. Then, Faraday’s constant will let us convert that charge into moles of electrons. We must be careful with units, however, because the ampere is charge per second and time is given here in minutes.

Equation 13.8

Charge Current X Time Q=Ixt =
