2. Compute the half-wave potential for the reduction of Fe to Fe in 0.1 M KCIO4 at 3+ 25 °C. To d...
Compute the half-wave potential for the reduction of Fe3+ to Fe2+ in 0.1 M KClO4 at 25 o C. To do so use: (i) the standard potential for the Fe3+/ Fe2+ couple (ii) diffusion coefficients of Fe3+ and Fe2+, calculated from molar ionic conductivities (iii) activity coefficients, calculated from the Debye-Hückel limiting law
When answering Parts a-h, consider only the molecules and ions, Fe^2+(aq), Cd(OH)2(s), SO4^2-(aq), Al(s), I^-(aq), and Cr2O7^2-(aq), under standard state conditions. (1 pt each) Use standard reduction table. a) Which of these molecules and ions are oxidizing agents? b) Which of these molecules and ions are reducing agents? c) List the oxidizing agents from part a in DECREASING order of oxidizing agent strength. (strongest OA to weakest OA) d) List the reducing agents from part b in DECREASING order of...
*redox reactions in electeochemical cells* c) Fe/0.1 M FeSO4//0.1 M CuSO4/Cu I soaked a porous cup in tap water for a few minutes and then i let it stand in a 100 ml beaker containing 10ml of 0.1 M FeSO4. I added enough 0.1M CuSO4 to the cup until the two liquid levels were the same height. I inserted a zinc strip into the 0.1 M FeSO4 and a shiny copper strip into the 0.1 M CuSO4. I connected the...
