Study of hydrolysis of surcrose, progress of this reaction is monitored with the help of polarimeter because a solution of sucrose is dextrorotatory and on hydrolysis, the mixture of products obtained becomes laevorotatory. That's why this reaction is also known as inversion of cane sugar.

Initially, a solution of 0.025 moles of sugar in 200 gm of water was taken. After 54 minutes the solution shows depresion in freezing point 0.372°C. (K_f(H₂O) = 1.86 K kg mol^-1)
