No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.

Does using benedicts reagent on honey produce a positive result?

Yes, Benedict's reagent can produce a positive result when used on honey containing reducing sugars, such as glucose or fructose. The reagent will change color from blue to green, yellow, orange, or red depending on the concentration of reducing sugars present in the honey.


How do you tell the difference between glucose and maltose using benedicts reagent?

Benedict's reagent can be used to differentiate glucose and maltose based on their reducing sugar properties. Glucose is a monosaccharide and will readily reduce Benedict's reagent to form a brick-red precipitate, indicating a positive test. Maltose, being a disaccharide composed of two glucose units, will also react with Benedict's reagent but may produce a less intense color change compared to glucose due to its structure.


How many grams of glucose are required to produce fifty milliliters of a 0.1 mole solution?

You need 0,9 glucose.


What tests are used to test for the presence of starch and glucose?

for the starch iodine test is performed in which the starch reacts with iodine to produce dark blue colour which confirms the presence of starch. for glucose benedict's and fehling's test is performed. benedict's test: 1 ml sample is mixed with 1 ml of benedicts solution and the heated upto boiling if the colur changes to brick red then it confirms the presence of glucose fehling's test: similarly 1 ml fehling's solution I & fehling's solution II each in taken together and to it 1 ml of the sample is takenon then heated uptill boiling. if the colour changes to brick red the it confirms the presence of glucose.


Will lipids give positive result from Benedict's solution?

No, lipids will not give a positive result with Benedict's solution. Benedict's test is used primarily to detect reducing sugars, such as glucose and fructose, by forming a colored precipitate when heated in the presence of these sugars. Lipids do not contain the necessary functional groups that react with Benedict's reagent, so they do not produce a color change.


What kind of compounds produce ions in solution?

Salts produce (metallic) positive catIONS and negative anIONS (of non-metals)


Will l-fucose produce positive in the Benedicts test?

L-fucose will not produce a positive result in the Benedict's test. The Benedict's test is designed to detect reducing sugars, and while L-fucose is a sugar, it does not have the necessary functional groups to act as a reducing agent. Therefore, it will not react with the copper ions in the Benedict's reagent to form a colored precipitate.


Why does starch produce a negative result with Benedict's reagent?

Benedict test have a negative result in glycogen because glycogen is a polysaccharide. Benedict test is meant for testing reducing sugars. It can also give positive results in the case of disaccharide or monosaccharide.


What is the glucose test result of streptococcus faecalis?

It is positive for the metabolizing of glucose.


How many moles of H2O are needed in order to produce 1 mole of glucose?

You need to dissolve 180 grams of glucose in water and make it up to 1000ml. this produces 1 M Glucose solution.


How does Benedicts test indicate hydrolysis of sucrose and starch?

Benedict 's solution contains Copper , which can accept electrons from reducing sugars and consequently change color. A positive Benedict's sugar test will produce an orange to brick-red color. Reducing sugars have either a free aldehyde functional group or a free ketone functional group as part of their molecular structure; starches and other polysaccharides lack these functional groups . If Benedict's test changes color ( pos. reaction ) polysaccharides must be hydrolyzed.


How do you know that glucose is a compound?

Glucose is a compound made up of the elements carbon, oxygen and hydrogen. Glucose solution in water is a mixture of water molecules and glucose molecules. Mixing them doesn't produce any new substance, and you can separate them without creating any new molecules.
