What is the weight of nickel deposited on an iron article of 20cm2 by passing a current of 5 A for 500 seconds?

Text Solution

Verified by Experts

Mass of substance deposited electrolytically, W= Zlt (Faraday.s first law)
Equivalent mass of nickel, E= 29.36
Electrochemical equivalent of nickel, `Z= (E )/(96500) = (29.36)/(96500)`
Mass of nickel deposited electrolytically, `W= (29.36g)/(96500C) xx 5A xx 500s = 0.86g`
