the equation for this are?
aldehyde + acidified potassium permanganate
RCHO + 2KMnO4 + H2SO4 → RCOOH + K2SO4 + 2MnO2 ↓+ H20
aldehyde + Tollen's reagent
RCHO + 2AgNO3 + 2NH4OH → RCOOH + 2Ag↓ + 2NH4NO3 +H2O
aldehyde+ Fehling's reagent
RCHO + 2CuSO4 + 4NaOH →RCOOH + Cu2O↓+ 2Na2SO4 + 2H2O
THAT's ALL I KNOW
aldehyde + Sodium Hydrogen Sulfite

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.
Which compound gives positive Fehlings test?
Fehling test is used for reducing sugars.
Why does the fehlings solution turn red?
When Fehling's solution is added to an aldehyde it turns brick red
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.
Why is it important that fehlings solution be freshly prepared?
Fehling's solution must be freshly prepared because there is a tendency for it to oxidize if not used right away
What is fehlings solution?
Fehling solution "A" is copper sulphate solution and Fehling solution "B" is a solution of sodium potassium tartrate and NaOH.
What chemical formula for Fehlings reagent?
The Fehling A solution contain copper sulfate.The Fehling B solution contain sodium potassium tartrate and sodium hydroxide.

Which is more sensitive test fehlings test or Benedicts test?
benedicts test

explain using sample equation, the application of benedicts tollens and fehlings test in hospital?
wrt
Why does the fehlings solution turn red?

Are substance considered reducing fehlings test also the substance reducing in benedicts test?
yes.

After hydrolysis did sucrose give a positive test with fehlings test why orwhy not?
After hydrolysis sucrose did give a positive test. It reduces sugar that has hemiketal and hemiaetal in it.
