- Definition analytical chemistry technique that allows the user to find the concentration of a reactant by reacting it with an excess volume of reactant of known concentration. The resulting mixture is then titrated, taking into account the molarity of the excess that was added Reference "Wikipedia > Back titration. http://en.wikipedia.org/wiki/Back_titration [27.4.2011]"
- Comment This is used as opposed to standard volumetric titration when the substance being analyzed is either too weak to give a valid reaction, or too slow.A back titration is useful if the endpoint of the reverse titration is easier to identify than the endpoint of the normal titration.Back titration is also useful when trying to work out the amount of an acid or base in a non-soluble solid.
