Question

What is the rate of electroplating in a cell with a current of 2.5 A passing through it for 1 hour if the mass of the metal deposited on the cathode is 0.456 g? (assume a 100% yield and use the appropriate formula to calculate the rate).

Answer 1

To calculate the rate of electroplating, we can use the formula:Rate of electroplating =  Mass of metal deposited  /  Current  Time First, we need to convert the time to seconds:1 hour = 60 minutes  60 seconds/minute = 3600 secondsNow, we can plug in the values into the formula:Rate of electroplating =  0.456 g  /  2.5 A  3600 s Rate of electroplating = 0.456 g / 9000 AsRate of electroplating = 0.00005067 g/AsThe rate of electroplating in the cell is 0.00005067 g/As.
