Question

Which of the following is used to separate glucose and fructose from hydrolysate of sucrose?

Options

• Adding ethanol during cooling

• Adding water during cooling

• Adding dilute hydrochloric acid

• Adding dilute sulfuric acid

Answer 1

Adding ethanol during cooling

Explanation:

The hydrolysate of sucrose refers to the solution obtained by breaking down sucrose (a disaccharide) into its constituent monosaccharides, glucose and fructose, through hydrolysis. Glucose is then separated from fructose by adding ethanol during cooling. Glucose, being almost insoluble in alcohol, crystallises out first.
