Homework Help: Chemistry: Combined Acid-Base and Redox Titrations

  1. Feb 4, 2010 #1
    1. The problem statement, all variables and given/known data
    Determine acid concentration of a mixture of (COOH)2 and H2SO4 by titration against NaOH
    Concentration of NaOH = 0.2M
    Average Titre Figure (NaOH) = 8.93cm3
    Volume of mixture added = 10mL

    2. Relevant equations
    2NaOH + (COOH)2 [tex]\rightarrow[/tex] 2NaCOO + 2H2O


    3. The attempt at a solution
    Reaction ratio NaOH: (COOH)2:H+ions = 2:1:2
    Molarity of NaOH 0.2M
    Moles of NaOH in 8.93mL = 1.786 x 10-3 mol
    Moles of H+ ions = 1.786 x 10-3 mol in 10mL

    A similar calculation for H2SO4. Then do you just add the moles and express in mols/L?
