The sucrose does not react with Fehling's reagent. Sucrose is a disaccharide of glucose and fructose. Most disaccharides are reducing sugars, sucrose is a notable exception, for it is a non-reducing sugar. The anomeric carbon of glucose is involved in the glucose- fructose bond and hence is not free to form the aldehyde in solution.

Is sucrose soluble in sodium hydroxide?
Yes, sucrose is soluble in sodium hydroxide. When mixed with sodium hydroxide in water, sucrose will dissolve to form a clear solution.
What is the color of the fehlings solution?
Fehling's solution is typically blue in color due to the presence of copper ions. When Fehling's solution is mixed with reducing sugars, such as glucose, it turns from blue to brick-red or yellow-brown due to the formation of a copper oxide precipitate.
If 25 moles of sucrose are mixed into 50 liters of water what is the molarity?
The molarity can be calculated using the formula: moles of solute divided by liters of solution. In this case, the moles of sucrose is 25, and the liters of solution is 50. This gives a molarity of 0.5 M.
What is the color when fehling a and fehling b are being mixed?
When Fehling A and Fehling B solutions are mixed together, they form a clear blue solution due to the complexation of copper ions present in the solutions.
Why is sucrose an invert sugar?
Invert sugar is a combination of fructose and glucose often mixed with sucrose.
Why would sucrose be mixed with yeast cells?
oxygen
What is the product obtained by combining fehlings a and fehlings b solution?
The product obtained by combining Fehling A and Fehling B solutions is a mixture used for detecting reducing sugars. It is commonly used in the Fehling's test to identify the presence of aldehydes and alpha-hydroxy ketones in organic compounds.
What happens when silver nitrate is mixed with a solution of sodium chloride?
sh*t goes down...
How many mls of a syrup containing 85 of sucrose should be mixed with 150mls of a 60 sucrose syrup to make a syrup containing 80 sucrose?
37.5 mL
Is sugar and water a solution compound or heterogeneous mixture?
sucrose is a compound and every pure compound is always homogeneous.
Is sucrose dissolved in water an ionic compound?
No, sucrose dissolved in water is not considered an ionic compound. Sucrose is a molecular compound composed of carbon, hydrogen, and oxygen atoms, and when dissolved in water, it breaks down into its individual molecules. Ionic compounds, on the other hand, are composed of positively and negatively charged ions held together by electrostatic forces.
What happens when HCl is mixed with a solution that is not a buffer solution?
When HCl is mixed with a solution that is not a buffer solution, the pH of the solution will decrease significantly due to the addition of the strong acid. The excess H+ ions from the HCl will react with any available bases present in the solution, leading to a decrease in pH. The solution will become more acidic as a result.
