Balance each redox reaction occurring in basic aqueous solution. c. NO2-(aq) + Al(s) ¡ NH3(g) + AlO2-(aq)
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. Ni2+(aq) + Mg(s) ¡ Ni(s) + Mg2+(aq)
Calculate the standard cell potential for each of the electro- chemical cells in Problem 43.
Use line notation to represent each electrochemical cell in Problem 43.
Make a sketch of the voltaic cell represented by the line nota- tion. Write the overall balanced equation for the reaction and calculate Ec°ell. Sn(s) | Sn2+(aq) || NO( g) | NO3-(aq), H+(aq) | Pt(s)
Determine whether or not each redox reaction occurs spontaneously in the forward direction. a. Ni(s) + Zn2+(aq) ¡ Ni2+(aq) + Zn(s)
