Question #8494

Calculate how much chromium (as grams) can be electrodeposited in a one day when the current is 1.50 A. Solution contains Cr3+ ions.

Expert's answer

m = M_{w}*I*t/n*F

m - mass

M_{w} - molecular weight

n - the number of electrons involved in the process

I - electric current

F - Faraday constant

t - time

m = 51.996*1.5* (24 * 60 *60)/3*96 485.3 = 23.3 g

m - mass

M

n - the number of electrons involved in the process

I - electric current

F - Faraday constant

t - time

m = 51.996*1.5* (24 * 60 *60)/3*96 485.3 = 23.3 g
