15. Of the group 1 elements Li,K, and Na, which is the strongest reducing agent? 16. A voltaic cell is based on the reaction between Cu2+ and Ni metal to produce Cu metal and Ni2+. Write the balanced cell reaction. 17. A voltaic cell with a basic aqueous background electrolyte is based on the oxidation of Cd(s) to Cd(OH)2( s) and the reduction of MnO4−(aq) to MnO2( s). Write the balanced cell reaction. 18. Calculate the cell potential for the cells described in questions 16 and 17. 19. Starting with standard reduction potentials, calculate ΔG∘ and E∘ for each of the following reactions. a. 2Cu+(aq)→Cu2+(aq)+Cu(s) b. Cu(s)+2Fe3+(aq)→Cu2+(aq)+2Fe2+(aq) 20. Calculate E at 500 K for the cell based on the reaction Fe3+(aq)+Cu+(aq)→Fe2+(aq)+Cu2+(aq) when [Fe3+]=[Cu+]=1.50×10−3M and [Fe2+]=[Cu2+]=2.5×10−4M. 21. If the potential of the SHE is 0.000 V at pH=0.00, what is the potential of the same electrode at pH=7.000?
