Explanation:
Detailed explanation-1: -Benedict’s solution benedict Benedict’s solution is used to detect reducing sugars, typically monosaccharides or disacharides. It will show a positive result for reducing sugars such as glucose, fructose, lactose, maltose, galactose. It will show a negative result for non-reducing sugars such as sucrose, starch.
Detailed explanation-2: -Benedict’s Test is used to test for simple carbohydrates. The Benedict’s test identifies reducing sugars (monosaccharide’s and some disaccharides), which have free ketone or aldehyde functional groups. Benedict’s solution can be used to test for the presence of glucose in urine.
