GRAVIMETRIC ANALYSIS
Gravimetric analysis is used to determine the mass an element or compound
of
in a substance This is determined by converting the substance into another substance
of known chemical compisition which can be readily isolated and purified
This conversion can occur either through precipitation or volatilisation
NEEDTO BE FAMILIAR WITH
An accurate electronic balance t the tare function
A weighing boat
Weighing by difference
The term weighing accurately approximately
Heating to constant mass
heating a substance
allowing it to cool in a desiccator to prevent absorption of water
weighing it
repeating the steps of heating cooling and weighing until no further
changes in mass are observed
