What is a titration
Titration is a common laboratory method of
quantitative chemical analysis that is used to
determine the unknown concentration of a known
reactant. Because volume measurements play a
key role in titration, it is also known as volumetric
analysis. A reagent, called the titrant of a known
concentration and volume is used to react with a
solution of the titrand, whose concentration is not
known. Using a calibrated burette or chemistry
pipetting syringe to add the titrant, it is possible to
determine the exact amount that has been
consumed when the endpoint is reached. The
endpoint is the point at which the titration is
complete, as determined by an indicator.…read more

Endpoint
An endpoint titration is any scientific method that
uses a titrant, titrand and sometimes an indicator
solution to quantify the amount of reactant in a liquid
substance. The endpoint is when enough titrant has
been added to the titrand to facilitate a colour
change, or endpoint. The reactant can be quantified
because the concentration of the titrant is known
and the volumes of all solutions are recorded. An
endpoint titration uses a calculation to determine the
concentration of reactant in the solution. Every
method requires a unique calculation to find its
result.…read more

Types of Endpoint Titrations
There are several types of
titrations. The common acid-
base example has an endpoint
when the titrand is neutral or at
a pH conducive for the indicator
to change colour.…read more

Key words
A titrand is the solution (or other substance) which
one has in a conical flask or beaker into which the
titrant is titrated from a burette.

moles of solute per liter of solution.
