• Introduction
• Direct titration
• Requirements to reactions in direct titration
• Acid-base titrations
Introduction
• A direct titration is the basic titration
method that involves the reaction between
the unknown compound and the compound
with known concentration.
• The unknown compound is directly reacted
with the known compound.
• the end point of the titration indicates the
end of the reaction
Direct titration
• Direct titration is the most basic titration process
which involves a reaction between unknown
compounds with a known concentration
compounds.
• This type of titration does not involve the addition
of excess reagent; the unknown compound reacts
directly with the known compound.
• Direct titrations are used when the endpoint of
the titration can easily be obtained.
direct.ppt
Requirements to reactions in direct titration
• reaction involving the titrant and analyte
must be of known stoichiometry,
quantitatively
• the titration reaction must occur rapidly
• a suitable method must be available for
determining the end point with an
acceptable level of accuracy
• Reactions should proceed at room
temperature
• Titration should not be accompanied by
collateral reactions which deform the
results of the analysis
• Reactions should be specific
• a suitable indicator is available
Requirements to reactions in direct titration
Acid-base titrations
• Acid-base titrations are good examples for
direct titrations.
• an acid is reacted with a base. An indicator
is used to determine the end point of the
reaction since almost all acids and bases are
colorless compounds.
• With the progression of the reaction, the pH
of the solution is changed.
