STRONG AND WEAK ACIDS AND BASES

The amount of H+ ions an acid can give and the amount of OH- ions a base can give determines its
strength. Strong acids give large amounts of ions, they dissociate fully ­ for example, nitric acid,
hydrochloric acid and sulfuric acid are all…

TITRATION

This reaction is a type of neutralisation without adding any excess solution.
1. Add 25 cm3 of base, for example sodium hydroxide using a volumetric pipette into a flask.
2. Add few drops of phenolphthalein indicator to the flask, this indicator is pink in basic conditions.
3. Fill a…
