a. Use standard cell potentials to show what reaction wouldoccur if you placed a strip of Cr in a solution of equalconcentrations of NiCl2 and Al(NO3)3.
b. Zinc is plated onto iron to protect the iron from corrosionin a process called galvanization. How long would it take to plate100g of zinc onto “sheet metal” in a ZnCl2 bath running at acurrent of 7.5A?
Promise to rate! Much appreciated, thank you!
