Include your experimentally determined mole ratios as The entry for the silver(I)/silver(0) half-reaction is above that for the copper(II)/copper(0) half-reaction, and so the oxidation of Cu by Ag+ is predicted to be spontaneous (Ecathode > Eanode and so Ecell > 0). Created by Sal Khan. These coefficients also have the ratio 2:1:2 (check it and see), so this equation is balanced. BaCl2 (aq) + Na2SO4 (aq) ------> BaSO4 (s) + 2 NaCl (aq) Na and Cl experiment 4 mole to mole relationship between Cu and Ag Tabulations of E values for other half-cells measured in a similar fashion are available as reference literature to permit calculations of cell potentials and the prediction of the spontaneity of redox processes. Can someone tell me what did we do in step 1? A balanced chemical equation shows us the numerical relationships between each of the species involved in the chemical change. Example: How many moles of O are required to form 5.00 moles of HO? Table 17.1 provides a listing of standard electrode potentials for a selection of half-reactions in numerical order, and a more extensive alphabetical listing is given in Appendix L.
