Practice Problems: Galvanic Cells, part 1 1. Write half-reactions and a balanced equation for the cell reaction for the galvanic cell: (a) Ni(s)│Ni 2+ (aq)║ Ag + (aq)│Ag(s) (b) C(gr)│H 2 (g)│H + (aq)║ Cl - (aq)│Cl 2 (g) │Pt(s) 2. Write half-reactions, the balanced equation for the cell reaction, and the cell diagram for the following skeletal equations: (c) Cl 2 (g) + H 2 (g) → HCl(aq) (d) MnO 4 - (aq) + H + (aq) + Cl - (aq) → Cl 2 (g) + Mn 2+ (aq) + H 2 O(l) 3. Write the half reactions and devise a galvanic cell (write the cell diagram) to study the reaction H + (aq) + OH - (aq) → H 2 O(l) 4. (a) Write balanced reduction half-reactions for the redox reaction of an acidified solution of potassium permanganate and iron(II) chloride. (b) Write the balanced equation for the cell reaction and devise a galvanic cell to study the reaction (write its cell diagram). 5. Predict the standard emf of each of the following galvanic cells: (a) Pt(s)│Cr 3+ (aq),Cr 2+ (aq)║ Cu 2+
