    Yes the white solid is sodium propanoate

    Any idea what the vinegary smell was? What's the thing in vinegar that gives it that smell?

    Ethanoic acid gives the smell, doesn't it?
    But what else would be formed?

    Yes ethanoic acid is the smell in vinegar but here a similar compound is produced: propanoic acid.

    So now we know H2SO4 + CH3CH2COONa ---> CH3CH2COOH + X

    what must X be? i.e. what's on the left but not on the right?

    Is it NaHSO4?

    Yes that is one possible product :yep:

    But (depending on the amounts) that will react further to form Na2SO4

    So the equation they probably would want is: H2SO4 + 2CH3CH2COONa ---> 2CH3CH2COOH + Na2SO4
