Trommer's test is a chemical test used to detect the presence of reducing sugars in a sample. In the case of starch, which is a polysaccharide and not a reducing sugar, Trommer's test will typically result in a negative outcome. This is because starch does not contain a free aldehyde or ketone group required to react with the reagents used in the test.
Benedict's test is a test used to determine the presence of reducing sugars. Sucrose is not a reducing sugar that's why its color doesn't change. . .
Benedict's solution is a chemical reagent used to test for the presence of reducing sugars, such as glucose. When heated with a reducing sugar, such as glucose, in the presence of an alkali (sodium carbonate), a redox reaction occurs, causing the blue color of the Benedict's solution to change to a brick-red precipitate of copper oxide. The intensity of the color change is proportional to the amount of reducing sugar present in the solution.
A water bath is used during tests for reducing and non-reducing sugars to provide a controlled and consistent temperature for the reactions involved. This ensures that the enzymes or reagents react optimally, enhancing the accuracy and reliability of the test results. The gentle heat helps to dissolve substances and promotes the necessary chemical reactions without causing degradation or evaporation of the samples.
It is a chemical reagent used to differentiate water-soluble carbohydrates and ketone functioning groups. Its also a test for reducing and non-reducing sugars.

Sucrose gives a negative reaction to the Benedict's reagent test because it is a non-reducing sugar. Benedict's reagent is used to test for the presence of reducing sugars, which have the ability to reduce the copper ions in the reagent. Since sucrose does not have this ability, it does not give a positive reaction.
Benedict's test estimates on color scale the presence of sugar .Normally used as a random pathological chemical test to determine the presence of sugar in urine in diabetes patients.In presence of sugar Benedict's solution turns from blue to shades of yellow,red,brown & dark according to the percentage of sugar present in solution on heating the solution.

Dilute hydrochloric acid is used to hydrolyze the non-reducing sugar into its constituent monosaccharides. This step is necessary before performing the Benedict's test for reducing sugars, which can only detect monosaccharides or reducing disaccharides. After hydrolysis, the presence of reducing sugars can be confirmed by the appearance of a red precipitate in the Benedict's test.
Trommer's test is a chemical test used to detect the presence of reducing sugars like glucose. In the test, a brick-red precipitate of cuprous oxide (Cu2O) forms when reducing sugars are present in the sample.
Benedict's solution is commonly used to test for the presence of reducing sugars. When a reducing sugar is present, the solution changes color from blue to green, yellow, orange, or red, depending on the amount of sugar present.
