Description Consider a galvanic cell in which Al3 is reduced to elemental aluminum, and magnesium metal is oxidized to Mg2 . Write the balanced half-cell reactions that take place at the cathode and at the anode.
Description [Cu(NH3)4] 2+ solutions exhibit a deep blue-violet color. How can you use spectrophotometry to confirm that this reaction has occurred and that the product formed is in fact tetraamminecopper(lI)sulfate. Would you expect the wavelength of maximum absorbance (?max) for Cu(NH3)4 2+ to be greater than or less than ? max for Cu(H2O)6 2+? Explain.
