Question:

Given these half-cell reactions and associated standard reduction potentials, answer the questions that follow:

[Zn(NH3)4]+ (aq) + 2 Ti+ (aq) + e e Zn(s) + 4 NH3(aq) E -1.015 V 2+ Sn+ (aq) + 2 e Ti+ (aq) O2+ (aq) + 2 H+

(a) Determine which pair of half-cell reactions leads to a cell reaction with the largest positive cell potential, and calculate its value. Which couple is at the anode and which is at the cathode?

(b) Determine which pair of these half-cell reactions leads to the cell with the smallest positive cell potential, and calculate its value. Which couple is at the anode and which is at the cathode?
