?Sketch a voltaic cell for each redox reaction. Label the anode and cathode and indicate

Chapter 20, Problem 44

(choose chapter or problem)

Sketch a voltaic cell for each redox reaction. Label the anode and cathode and indicate the half-reaction that occurs at each electrode and the species present in each solution. Also indicate the direction of electron flow.

a. \(Ni^{2+}(aq) + Mg(s) \rightarrow Ni(s) + Mg^2+(aq)\)

b. \(2 H^{+}(aq) + Fe(s) \rightarrow H_{2}( g) + Fe^{2+}(aq)\)

c. \(2 NO_{3}^{-}(aq) + 8 H^{+}(aq) + 3 Cu(s) \rightarrow 2 NO( g) + 4 H_{2}O(l) + 3 Cu^{2+}(aq)\)

Text Transcription:

Ni^2+(aq) + Mg(s)  Ni(s) + Mg^2+(aq)

2 H^+(aq) + Fe(s)  H_2( g) + Fe^2+(aq)

2 NO_3^-(aq) + 8 H^+(aq) + 3 Cu(s)  2 NO( g) + 4 H_2O(l) + 3 Cu^2+(aq)
