What quantity of nickel would we obtain by the electrolysis of an acid solution of NiCl2, if: the electrolysis time is 30min; the electrolysis potential is 2.5V; the polarization potential is 2V; the cell's resistance is 0.5Ω; and the current efficiency is 75%.

Thank you for the opportunity to help you with your question!

Ed=-E+Ep+RI

Ep= The polarization potential of a cell

-E= the cells potential

NI 2/N1   gives E -1.48

R1=2.5+-1.48-2.0

R1=2.5-1.48-2.0=

-1.98v

Please let me know if you need any clarification. I'm always happy to answer your questions.
