- equivalence point
- The point in a titrationThe gradual addition of one solution to another until the chemical amount of one reactant being added matches stoichiometrically the amount of another reactant in the solution initially present. at which the amount of one reactantA substance consumed by a chemical reaction. being added stoichiometrically matches the amount of another reactant initially present. The end pointIn a titration, the minimum volume of titrant that must be added to cause a sudden change in a physical property (such as color of an indicator, pH, conductivity, or absorbance). The end point should match the equivalence point as closely as possible should match the equivalence pointThe point in a titration at which the amount of one reactant being added stoichiometrically matches the amount of another reactant initially present. The end point should match the equivalence point as closely as possible. as closely as possible.
