(July 2013) </Td> </Tr> <P> 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 . </P> <P> The endpoint (related to, but not the same as the equivalence point) refers to the point at which the indicator changes colour in a colourimetric titration . </P>
