Answer Posted / subash
First thing is that clean the burette about 3 to 4 times
with disttled water for removal of air gaps or previous
solution.
After sufficient cleaning fill the bureete with distilled
water and make sure that there is no bubbles formation this
lead to misreading.
First weigh the required volumetric flask similar to the
didpensing burette volume using balance i.e initial weight
Dispense the disttled water completely in to volumetric
flask and weigh the volumetric flask again i.e Final weight
Actual weight= Final weight-Initial weight
The weight can be converted to Volume using formula
Density=mass/volume
Density changes with temperature and note the down the
temperature at which calibration is done.
