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 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.
How do you neutralize Boric Acid in water?
To neutralize boric acid in water, you could add a weak base, such as baking soda (sodium bicarbonate), to the solution. The base will react with the acid to form a salt and water, which reduces the acidity of the solution. Ensure to add the base slowly and stir the solution to effectively neutralize the boric acid.
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.
