    The 'real' answer is complicated and depends on the two dissociation constants of sulphuric acid.

    The expected answer is 2 x 0.25 x 1

    How do you find the concentration of the undiluted solution of the acid in titrations? If possible, could you explain it in terms of ratios e.g. 11.2cm3 (result of titre) : 0.002654 mol (moles in that amount).
