Find the thickness of a nickel layer deposited on an article with surface area of `1200cm^(2)` in the course of a 6-hour electrolysis at a current of 10.5 A.

Answer

`65mum`

Explanation

The mass of material deposited on the cathode is `rhoSd=(Ail)/(eN_(A)Z)` the valence of nickel is Z=2. The remaining information is contained in the statement of the problem and in the tables.
