    Comparing these four reactions, would number 1 be the best way to produce salt or number 4?

    I am slightly confused as the last one leaves hydrogen behind as a gas, although it has the highest percentage yield.


    Thanks in advance

    In terms of purity and percentage yield

    Is a reaction which has 99% yield and purity the best if it takes 6 years to go to completion?

    Define the term purity.

    Since none of them are equilibria they would all give 100% yield (apart from product lost in the separation stage).

    All of them, I would imagine, are done with HCl(aq), so all would produce NaCl(aq) and all would need separating the same way, so all would have the same yield and give equally pure product. All would have to be carefully reacted to ensure molar ratios of reactants, as each of the sodium containing reactant would dissolve.

    Of the four, I'd do #2, since you can just do a titration. That'd be my best way.
