1. Angle of rotation of Sucrose solution :
Weigh and transfer accurately 10 g of previously dried Sucrose AR to a 100 ml volumetric flask, dissolve and dilute with water and mix (10 %).
Make the different concentrations of Sucrose solution 20%, 30%, 40% and 50% in the same manner like 10 %.
Balance ID: __________________.
Sucrose AR, Make: _________________, Valid up to :________________.
10 % w/v Sucrose AR Solution: _______________ g Sucrose AR –> 100 with water
20 % w/v Sucrose AR Solution: _______________ g Sucrose AR –>100 with water
30 % w/v Sucrose AR Solution: _______________ g Sucrose AR –>100 with water
40 % w/v Sucrose AR Solution: _______________ g Sucrose AR –> 100 with water
