Consider the following liquid junction cell at room temperature: where the left side of the cell contains an electrolyte solution at 9.26 x 10^â2 M and the right side of the cell contains an electrolyte solution at 7.32 x 10â2 M solution.
Zn(s) | ZnSO4(aq) k CuSO4(aq) | Cu(s)
(a.) Calculate the observed cell potential (εcell) using the Nernst Equation and concentration. (b.) Calculate the observed cell potential (εcell) using the Nernst Equation, the Debye-Hückel Limiting Law, and ionic activities. (c.) Briefly describe the observed differences between the two calculations. Comment if these differences are significant and if that seems logical based on the conditions of liquid junction cell (1 paragraph maximum, typed only, 1.5 line spacing, 12-point font).
