Assignment:
An iron sample (surface area of 3.3 cm^2) was protected by nickelization in a solution containing 0.1 M NiSO4 and 1 M H2SO4 at a current of 0.28 A for 30 min.
What will be the sample weight increase after the process of nickelization upon 62% current efficiency?
Provide complete and step by step solution for the question and show calculations and use formulas.
