§76 Reversible cell 7.6.6 Cell design Principle for cell design: To harvest useful energy, the oxidizing and reducing agent has to be separated physically in two different compartments so as to make the electron passing through an external circuit EXAMPLES: (2) Steps for Reversible Cell Design 1. Separate the two half-reactions 1 Zn+ cuso,= Znso, +Cu 2. Determine electrodes and electrolytes 2 Agt(m)+ CI(m)=AgCl(s) 3. Write out cell diagram 3 HO=H++oH 4.
