Sulfuric was titrated with NaOH solution. 208 mL of .250 M NaOH solution was needed to completely neutralize 65.0 mL of H2SO4. What is the concentration of the sulfuric acid solution?

  • chemistry -

    2NaOH + H2SO4 ==> Na2SO4 + 2H2O

    Moles NaOH used = M x L = ??
    Moles H2SO4 needed = 1/2 moles NaOH (from the equation).
    M H2SO4 = moles H2SO4/L H2SO4.

  • chemistry -

    0.4 mol/L or 0.4M
