25.00mL of an unknown sulfuric acid solution is titrated to the second equivalence point with 21.02mL of 0.420M potassium hydroxide solution. What is the concentration of the sulfuric acid solution?

  • Chemistry titrations -

    H2SO4 + 2KOH ==> K2SO4 + 2H2O
    mols KOH = M x L = ?
    mols H2SO4 = 1/2 mol KOH (see the coefficients)
    M H2SO4 = mols H2SO4/L H2SO4
