Redox Titration Help

  1. Jun 22, 2010 #1
    To determine the concentration of Fe (aq)2+ by a redox titration, we could use an acidified
    standard solution of

    A. Sn2+
    B. Pb2+
    C. HCl
    D. H2O2

    I know the answers H2O2, but i dont know how to get it. How doe redox titrations work?

    Redox titration works as every other kind of titration. You need to select reaction with well known stoichiometry and react substance that you want to determine with substance of know concentration, somehow detecting the moment when amount of the substance added was stoichiometric.

    In this particular case you need to select substance that is able to react with Fe2+, oxidizing it to Fe3+. Not much choice.
