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.
When Fehling's solution is mixed with glucose, a reducing sugar, a redox reaction occurs. The copper(II) ions in Fehling's solution are reduced to copper(I) oxide, resulting in the formation of a red precipitate. This change indicates the presence of reducing sugars, as glucose donates electrons during the reaction. The appearance of the red precipitate confirms the positive result for reducing sugars in the solution.
No, sucrose is not soluble in sodium hydroxide without water.
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.
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.
When Fehling A & B are mixed in equal quantities... Fehlings Reagent is formed which is DEEP BLUE in colour Hope that answers your question! :)
Invert sugar is a combination of fructose and glucose often mixed with sucrose.
oxygen
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.

sucrose is a compound and every pure compound is always homogeneous.
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.
