Answer / nagendra rane
Specific Optical Rotation [α]tλ = 100 x a
---------
l x C
Where Specific Optical Rotation at temperature âtâ and âλâ
is wavelength
a = Optical Rotation
l = length of Polarimeter tube
c = Concentration
The average Specific Optical Rotation of Dextrose
α = +52.76
Therefore C = 100 x a (Optical rotation)
---------------------------
2 x α
C = 100 x a (Optical rotation)
---------------------------
2 x 52.76
C = a X 0.9477
Concentration of Dextrose(C)= OR(a) x 0.9477
