Question #8490

Calculate how thick layer of nickel is formed on a metal plate when a current of 100 m A is lead 30 mins through a solution containing Ni2+-ions. The area of the plate is 0.10 m2.

Expert's answer

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

m - mass

M_{w} - molecular weight

n - the numberof electronsinvolved in the process

I - electric current

F - Faraday constant

t - time

m = 58.69*0.1*(30*60)/2*96485.3 = 0.05475

density is 8.908 g/cm^{3}

V = 0.05475/8.908 = 0.0061456 cm^{3}

h = 0.0061456/0.1 = 0.061456 cm or 0.61456 mm

m - mass

M

n - the numberof electronsinvolved in the process

I - electric current

F - Faraday constant

t - time

m = 58.69*0.1*(30*60)/2*96485.3 = 0.05475

density is 8.908 g/cm

V = 0.05475/8.908 = 0.0061456 cm

h = 0.0061456/0.1 = 0.061456 cm or 0.61456 mm
