Answer / bhagavanji nelakanti
Reasons to use sucrose solution for calibration of
polarimeter :
Sucrose is a disaccharide, mixture of both glucose and
fructose has a fixed rotation value which can calibrated with
10%, 20% and 30% sugar value, and remains constant for those
concentration for a little time only, upto that we can have a
very sharp reading calibration of pure sugar.
It is Very Easily prepared, most cheap at cost and having no
muta rotation

Answer / kesavareddy
sucrose do not show muta rotation. i.e it's rotation value
not changes with time. also shows linear values with
incresing concentrations
