The cell in Figure 17.3 is galvanic, the spontaneous cell reaction involving oxidation of its copper anode and reduction of silver (I) ions at its silver cathode: cell reaction: Cu ( s) + 2 Ag + ( a q) Cu 2+ ( a q) + 2 Ag ( s) anode half-reaction: Cu ( s) Cu 2+ ( a q) + 2 e cathode half-reaction: 2 Ag + ( a q) + 2 e 2 Ag ( s . are not subject to the Creative Commons license and may not be reproduced without the prior and express written 1. The previous section described the spontaneous oxidation of copper by aqueous silver(I) ions, but no observed reaction with aqueous lead(II) ions. Since by convention electrode potentials are for reduction processes, an increased value of E corresponds to an increased driving force behind the reduction of the species (hence increased effectiveness of its action as an oxidizing agent on some other species). The positive value for the standard cell potential indicates the process is spontaneous under standard state conditions. 390.233-185.000= 205.233g Mole is a term like dozen - a dozen eggs, a dozen cows, no matter what you use dozen with, it always means twelve of whatever the dozen is of.
