Depends on the Sugar:
Reducing sugars a normally monosaccharides but there are some disaccharides too like maltose.
If its a reducing sugar then you would add Benedicts Reagent (alkaline copper(II) sulphate). You then heat it. if a reducing sugar is present then a precipitate is formed that will be red/orange.
A Non-reducing sugar like Sucrose can be tested by first adding benedicts and heating. if no change is present you then add hydrochloric acid to hydrolyse the glycosidic bond. you then add a hydrogen carbonate solution to neutralise the acid. Then repeating the Benedicts and Heating process.

What is the difference between iodine solution and Benedict's solution?
Iodine solution is used to test for the presence of starch, turning blue-black in the presence of starch. Benedict's solution is used to test for reducing sugars such as glucose, turning from blue to brick red in the presence of reducing sugars.
Does iodine test for sugars?
Yes, the iodine test can be used to test for the presence of starch, not sugars. Iodine reacts with starch to form a blue-black color, indicating its presence. Sugars typically do not react with iodine in this way.
What is Benedict's solution used for?
Benedict's solution is most commonly used for testing if sugars are present in any enzyme, or solution, that contains starch. ex. Water + Starch Then test for sugars with benedict's.
Why you used sodium acetate in osazone test?
Sodium acetate is used in the osazone test to provide an alkaline pH environment for the reaction to occur. This helps in the formation of a crystalline precipitate from the reaction of sugars with phenylhydrazine, aiding in the identification of specific sugars based on the characteristics of the precipitate formed.
What is the name of chemical test for oxygen?
The chemical test for oxygen is the glowing splint test. In this test, a glowing splint is extinguished in the presence of oxygen due to its ability to support combustion. If the splint reignites, it indicates the absence of oxygen.
What is the product formed in trommer'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.
what is fehling test?
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.
What chemical indicator is used to test for monosaccharide?
Benedict's solution is commonly used as a chemical indicator to test for the presence of monosaccharides. It changes color from blue to green, yellow, orange, or red in the presence of reducing sugars such as glucose and fructose.
What is chemical formula of nylander's test?
equation involved in nylander's test using fructose
What test is used to test for sugars in a food?
Benedict's test using Benedict's Solution.
What is the name the reagent used to test reducing sugars?
Benedict's reagent is commonly used to test for reducing sugars. It is a blue solution that changes color to green, yellow, orange, or red in the presence of reducing sugars.
What is the difference between iodine solution and Benedict's solution?
Iodine solution is used to test for the presence of starch, turning blue-black in the presence of starch. Benedict's solution is used to test for reducing sugars such as glucose, turning from blue to brick red in the presence of reducing sugars.
What is the chemical basis of the Anthrone test?
The Anthrone test is based on the reaction between anthrone and carbohydrates, particularly simple sugars like glucose, to form a blue-green complex. The reaction occurs in acidic conditions and is commonly used to quantify the amount of sugars present in a sample.
Which compound gives positive Fehlings test?
Fehling test is used for reducing sugars.
What is the reagent used to test for complex sugars?
benidict's solution
What is the importance of phenylhydrazine test?
The phenylhydrazine test is important in identifying the presence of sugars, specifically aldose sugars in a sample. It forms osazone crystals with aldose sugars that are characteristic and can help determine the type of sugar present. This test is commonly used in biochemical and food analysis to detect the presence of reducing sugars.
Does iodine test for sugars?
Yes, the iodine test can be used to test for the presence of starch, not sugars. Iodine reacts with starch to form a blue-black color, indicating its presence. Sugars typically do not react with iodine in this way.
