Question 7 • Chemistry

The equivalence point in a titration refers to the point when

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

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.
