Fehling's A and Fehling's B are used together in the Fehling's test to detect the presence of reducing sugars, such as glucose. Fehling's A is a copper(II) sulfate solution, while Fehling's B is a complex solution of potassium sodium tartrate and sodium hydroxide. They work together to oxidize the sugar, causing a color change that indicates the presence of a reducing sugar.
What else can I help you with?
What is the fehlings test of glucose?
ulo nyo!!
What chemical formula for Fehlings reagent?
The Fehling A solution contain copper sulfate.The Fehling B solution contain sodium potassium tartrate and sodium hydroxide.
Why the oxidation of formic acid gives red precipitate while the oxidation of acetic acid not?
I think you are referring to the test using Fehlings solution. Fehlings solution oxidises aldehydes and ketones and formic acid and is in turn reduced. The red precipitate is the copper(I) oxide formed by reduction of the copper(II) complex found in Fehlings solution. Acetic acid is not readily oxidised and so there is no precipitate. See link for more information on what the complex is in Fehlings solution and how it is prepared.
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.
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! :)
Which compound gives positive Fehlings test?
Fehling test is used for reducing sugars.
What is the original colour of fehlings a solution?
Fehling's A solution is blue in color due to the presence of copper sulfate.
What is the original colour of fehlings solution?
Fehling's solution is originally blue in color due to the presence of copper ions.
Somthing you keep warm with that starts with b?
Something that is used to stay warm that starts with the letter B could be a blanket.
Is honey a reducing sugar or non reducing?
yes because honey is a monosaccharide All monosaccharides reduce weak oxidizing agents such as Cu2+ in fehlings's reagent.
What is the sum a and b?
If both are unknown, you have to keep it as a+b. If they're known, just add them
