Question 3 • Chemistry

The equivalence point in a titration refers to the point when

Answer
A
the number of moles of one reactant reacts completely with the moles of the other reactant.
B
the molarity of the acid used in the reaction equals the molarity of the base used in the reaction.
C
the acid in the flask turns clear.
D
the mL of the acid equals the mL of the base.

Explanation

At the equivalence point, the acid and base have reacted in the exact stoichiometric amounts required by the balanced chemical equation. For a 1:1 reaction, this means equal moles; for other reactions, the mole ratio may differ. Equal molarities or equal volumes are not required, so choice A is correct.
