a solution of sulphuric acid is titrated (allquot 20.0ml) with a solution of sodium hydroxide (0.1234M) 26.73ml of the base being required to the end point with phenolphthalein. calculate the molarity of the sulphuric acid solution

  • chemistry -

    2NaOH + H2SO4 ==> 2H2O + Na2SO4

    moles NaOH = M x L = ?
    Convert moles NaOH to moles H2SO4 by using the coefficients in the balanced equation. That will be
    ?moles NaOH x (1 mole H2SO4/2 moles NaOH) = ?moles NaoH x (1/2) = x moles H2SO4.
    Then M H2SO4 = mols H2SO4/L H2SO4.
