Which of the following must we know when we carry out a titration?
the stoichiometric ratio of the reactants
both (a) and (b)
neither (a) nor (b)
Answer:
Answer is B. One must know the stoichiometric ratio of the reactants. Otherwise, it would be difficult to calculate for the concentration of the unknown.
Neither need be known - that is the point of a titration.
You need the concentration of one of the reactants and the stoichiometric ratio then from the titration you can calc. the concentration of the other reactant.
