LESSON OBJECTIVE: Investigate the relationship between concentration and cell potential both qualitatively and, using the Nernst equation, quantitatively Download the slides and student led tasks for this lesson here: https://www.tes.com/teaching-resource... Learning Outcomes: (taken from the Cambridge International AS and A Level Chemistry curriculum) 24.2 Standard electrode potentials E⦵; standard cell potentials E⦵cell and the Nernst equation 6. deduce from E values the relative reactivity of elements, compounds and ions as oxidising agents or as reducing agents 7. construct redox equations using the relevant half-equations 8. predict qualitatively how the value of an electrode potential, E, varies with the concentration of the aqueous ions 9. use the Nernst equation, e.g. E = E⦵ + (0.059/z) log [oxidised species]/[reduced species] to predict quantitatively how the value of an electrode potential varies with the concentrations of the aqueous ions; examples include Cu2+(aq) + 2e- ⇌ Cu(s), Fe3+(aq) + e- ⇌ Fe2+(aq)
