Problem- Using standard reduction potential and cell potential to predict and explain which halogen, F2, Cl2, Br2, or I2, could NOT oxidize solid copper to form Cu 2+ ion? (hint: consider the redox reaction (unbalanced) X2 + Cu --> Cu2+ +X- and compare the standard cell potential E cell)
Solve the above problem and provide steps with explanation
