Copper (II) is the oxidizing agent in the following balanced redox reaction: I2 (s) + 5 Cu2+ (aq) + 6 H2O (l) → 2 IO3- (aq) + 5 Cu (s) + 12 H+ (aq)

For this question, answer it on your work paper. In the box below, type “complete” when finished. Make sure to show all of your work Consider the voltaic cell constructed using the following reaction: Ni (s) + Pb2+ (aq) → Ni2+ (aq) + Pb (s) Calculate the cell potential (Ecell) when [Pb2+] = 1.87 M and [Ni2+] = 0.420 M

Consider the following balanced redox reaction: H2SO3 (aq) + 2 Mn (s) + 4 H+ (aq) → S (s) + 2 Mn2+ (aq) + 3 H2O (l) Which element was oxidized during this reaction?
