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.

Harmful and unharmful effects of oxidation reaction?
my answer is that oxidation gives rise to rancidity and coorosion
What is the solute in vinger?
The solute in vinegar is acetic acid, which gives vinegar its sour taste and pungent odor. Acetic acid is produced through the fermentation process of ethanol by acetic acid bacteria.
Will precipitate dissolve in water?
A precipitate is the name for a solid which has formed from a solution - either through a reaction which gives an insoluble product, or by cooling of a saturated solution.
A reducing sugar gives a precipitate of silver metal with Benedict's reagent.?
This is probable an error.
Where a molecule gives up electrons and releases energy?
Oxidation
How do you distinguish between acetic acid and formic acid?
Formic acid gives positive result in both tollen's test and fehlings test. but acetic acid doesnot.
What precipitate will be formed when sodium acetate will be added with hydrochloric acid?
There shouldn't be any precipitate. Metathesis between those reactants gives sodium chloride (soluble) and acetic acid (also soluble).
What is the precipitate color of silver nitrate and barium chloride?
Silver chloride (AgCl) gives a white precipitate. Silver Bromide (AgBr) also gives a white precipitate, though it's a slightly more creamy white than the precipitate formed by AgCl. Silver iodide (AgI) gives a pale yellow precipitate.
Why does acetic acid and vinegar not mix well?
Acetic Acid is what gives vinegar it's sour taste so they do mix well as acetic acid is what makes vinegar.

Do acetic acid gives positive Tollents test?
Yes they do so.
Mild oxidation of a primary alcohol gives an?
Aldehyde
What is the test for barium ions?
Gives white precipitate when Sulfuric acid added!
What is oxidation of No in air gives?
air oxidation of air in an aqueous environment gives NO2 and traces of NO3.and finally gives NO2 and H+ by the result of chemical reaction 4NO + O2 +2H2O--------------------- 4NO2 + 4H+

What nutrient gives you the highest omount of energy?
Fat can gives highest amount of energy by its oxidation.
