Homework Help: [Chemistry] Calculation of Pt potential

  1. Apr 14, 2007 #1
    1. The problem statement, all variables and given/known data

    Calculate the potential of a Pt electrode immersed in a solution that is 0.0263M in K2PtCl4 and 0.1492M in KCl.
    The answer given in 0.78

    2. Relevant equations

    E = Eo - 0.05912/2 * log Q (Nernst Equation)
    3. The attempt at a solution

    We try looking at the reduction of PtCl4 with oxidation of Cl2, and came out with an answer, but its different from the answer key given.

    Maybe there is something with the oxidation/reduction of K?

    And not Pt+2/Pt? This is solution of complexed Pt+2, it must contain some free Pt+2. Not much, but that's where I would start.
