C7.05 Reasons for using titration
When an acid and an alkali react it is not possible to see the end of the
reaction unless an indicator is used. If an indicator is used the salt
made will be impure. Titration is used to find out exactly what volume of
acid and alkali should be mixed.
C7.06 Methods for carrying out titration
1.Fill a 25cm3 pipette up to the line with the alkali solution of
known concentration.
2. Transfer exactly 25.0cm3 of alkali to a conical flask and add an
indicator.
3. Rinse a burette with acid then fill it with the acid using a funnel.
Burette
4. Carefully run acid from the burette into the conical flask until the
indicator changes colour.
