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.

What is the product obtained by combining fehlings a and fehlings b solution?
When the two Fehling Solutions A and B are mixed, a deep blue solution containing a complex cupric ion is formed. On interaction with reducing compounds such as aldehydes or sugars, the copper is reduced to the univalent stage, and a red, yellow, or yellowish green precipitate is formed.
Is sucrose dissolved in water an ionic compound?
No, both sucrose and water are molecular compounds. When mixed together they form a solution or a homogeneous mixture.
If 25 moles of sucrose are mixed into 50 liters of water what is the molarity?
Molarity = moles of solute/Liters of solution Molarity = 25 moles sucrose/50 liters H2O = 0.5 M sucrose
What happens when HCl is mixed with a solution that is not a buffer solution?
If the solution is not a buffer, the HCl will react with the solution to form a product.
When an aqueous solution of lithium chloride is mixed with an aqueous solution of ammonium sulfate what happens?
No reaction occurs
What happens when you mixed the magnesium chloride solution with the sodium cabonate solution?
MgCl2 + Na2CO3 = 2NaCl + MgCO3
What happens when sodium chloride solution and carbon dioxide is mixed with spaghetti?
Macaroni
What happens when a solution of chlorine is mixed separately with potassium bromine solution and potassium iodide?
It is left as a low hazard
Why is sucrose an invert sugar?
Invert sugar is a combination of fructose and glucose often mixed with sucrose.
What is the color when fehling a and fehling b are being mixed?
When Fehling A & B are mixed in equal quantities... Fehlings Reagent is formed which is DEEP BLUE in colour Hope that answers your question! :)
Why would sucrose be mixed with yeast cells?
oxygen
