Title: Electrochemical Cells CheckOut


1
Electrochemical Cells Check-Out
  • Hand in Pre-Lab. Complex Report, GCF.
  • Determine relative reactivity of Mg/Cu/Zn with
    five solutions of H2SO4 , MgSO4 , CuSO4 , Na2SO4
    , and ZnSO4 .
  • Voltaic Cells Standard Cells (1 M) of
    (1) Cu/Zn , (2) Cu/Mg , (3) Zn/Mg.
  • Concentration Cells of Zn/Cu
    (4) 1 M ZnSO4 with 0.1 M CuSO4 ,
    (5) 0.1 M ZnSO4 with 1 M CuSO4 .

Effect of Concentration on Cell EMF
  • The Nernst Equation
  • The (simplified) Nernst equation at 298 K
  • n is number of moles of electrons.
  • Q Reaction Quotient

  • Purpose
  • Results
  • - Part A - Observations Balanced Equations
    for reactions that occurred
  • - Part B - Observations Balanced Equations
    Eo
  • - Part C - Voltages Explanations/Calculations
  • Show work for final voltages/equation i.e. show
    half-reactions with their potentials and how they
    add up to give overall reaction equation.
  • Conclusion Summary of results, Errors,
    Improvements
  • Individual Checked-Pre-labs
