Question

why there is colour change from Blue to white after addition of urine sample to Benedict's quantitative reagent. give specific reason​

Answer 1

Answer:

This reaction is caused by the reducing property of simple carbohydrates. The copper (II) ions in the Benedict's solution are reduced to Copper (I) ions, which causes the color change

Explanation:

Answer 2

Color change from Blue to white after the addition of the urine sample to Benedict's quantitative reagent

The reducing characteristic of simple carbohydrates is what triggers this reaction. Benedict's solution changes color as a result of the reduction of copper (II) ions to copper (I) ions.

Simple carbohydrates are tested for using Benedict's Test. With free ketone or aldehyde functional groups, reducing sugars are recognized by Benedict's test. You can check for the presence of glucose in urine using Benedict's solution.

Due to their ability to reduce other compounds by transferring hydrogens (electrons) to them, some sugars, like glucose, are referred to as reducing sugars. Benedict's reagent undergoes a color change as a result of a reduction reaction when heated in combination with reducing sugars. The hue ranges from lime green to brick-red based on the type and quantity of sugar.
