The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of bases and acids have been mixed. In other words, the moles of acid are equivalent to the moles of base, according to the equation (this does not necessarily imply a 1: 1 molar ratio of acid: base, merely that the ratio is the same as in the equation). It can be found by means of an indicator, for example phenolphthalein or methyl orange.\n\nAnswer this question based on the passage: when do we reach the equivalence point in the acid-base titration? Let's think fast. Stream of consciousness:

To answer the above question, the relevant sentence is: The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of bases and acids have been mixed. So the final answer is the point at which chemically equivalent quantities of bases and acids have been mixed.
