Volumetric Analysis
• AKA
Titrimetric Analysis
Volumetric analysis is first introduced by french chemist
Jean Baptiste Andre
Dumas,
Volumetric analysis is what type of analysis?
Quantitative analysis
Based
on
the
determination of the
volume of a solution
of known concentration
(standard) required to
react quantitatively with
a
solution
of
the
substance
to
be
analyzed.
Volumetric analysis
is one of the simplest
and oldest method of
quantitative
analysis
where the amount of
pure
substance
is
determined
by
quantitatively
reacting
with the titrant or also
known as volumetric
solution.
Titration
Volumetric solutions are Abbreviated “VS“ and known also as
Standard solutions
are solutions of
reagents
of
known
concentration
intended
primarily
for
use
in
quantitative determinations.
VS or Standard solutions
are solutions of
reagents in such solvents and of such
definite concentrations as to be suitable
for the specified purposes.
Test solutions
Auxiliary agents used to determine the
end point of titration.
Indicators
A species added to the analyte to give
an observable change at (which is the
endpoint) or near the end point.
Indicators
is a process of determining exact
concentration of a solution
Standardization
is a highly pure and stable
chemical reagent used to prepare standard
solutions, usually for titration and making
secondary standards and dilutions.
Primary standard
An alternative method is by the use of a
solution of known concentration and
allowing it to react equally with the
prepared solution which is called as the
Secondary standard
a highly characterized
material suitable to test the identity, strength,
quality
and
purity
of
substances
for
pharmaceutical use and medicinal products
