Titration Terms

Titration = chemical method of measuring how much of one solution is needed to react exactly with another solution with a known volume. It is performed firstly by measuring a quantity of an unknown substance (commonly called an analyte) it placing it into a suitable reaction container. Another solution with a known concentration is placed into a burette (which accurately pours out fine amounts). Both substances reach an end point which is determined by a colour change (with the use of an indicator ie phenolphthalein). The volume of titrant can be obtained from the burette and the concentration of the analyte can be found. Titrations involve both acidic and basic solutions.

Indicator = natural or synthetic substance that changes colour in response to the nature of its chemical environment. For example: alizarin, methyl red, and phenolphthalein
