Describe a chemical test to distinguish between ethanol and ethanoic acid

Hi Shreiyas !!!!!

To distinguish between ethanol and ethanoic acid ..... we can take a metallic carbonate or bicarbonate.........bcoz ethanoic acid on reaction wid the carbonate or bicarbonate produces CO2 gas while no such formation takes place wid ethanol....

we can identify CO2 bcoz they turn lime water milky......

Hope this helps !!!!!!!!

we can distinguish between ethanol and ethanoic acid by reacting them with a metallic carbonate like Na2CO3 or a bicarbonate like NaHCO3 .......

ethanoic acid reacts to give to give CO2 and no reaction takes place in case of ethanol.

2CH3COOH + Na2CO3 ----------> CH3COONa + H2O + CO2

CH3CH2OH +Na2CO3 -------------> NO REACTION...


HOPE U GOT IT........:)

litmus test -

blue litmus paper turns red in ethanoic acid and no change in alcohol.

KMnO4 test-

KMnO4 - pink in colour.

ethanoic acid - unsaturated carbon compound. 


alcohol  -saturated carbon compound.


If we add KMnO4 in  ethanoic acid - unsaturated carbon compound no colour change.But if addKMnO4 in alcohol  -saturated carbon compound there will be colour to brown precipetate from pink due to oxidation of ethanol.

litmus test is wrong because this methods is applicable to distinguish b/w saturated and unsaturated hydrocarbon....this test is called alkali ethanoic acid and ethanol both have double covalent bonds..!

when we add a base, such as sodium bicarbonate (NaHCO3)....also known as baking soda.

Ethanoic acid (also known as acetic acid) is the acidic component of vinegar. We all know what happens when we add baking soda and vinegar, right? Lots and lots of bubbles and foam (from the carbon dioxide released during the reaction):

NaHCO3 (s) + CH3COOH (ethanoic acid) -----> CH3COONa (aq) + H2O + CO2 (g)

Ethanol will not react with sodium bicarbonate..

I think Kamil is write and i am satiafied this answer .

1) litmus test >No change in colour of litmus solution in case of ethanol >Blue litmus solution turns red in case of ethanoic acid 2)sodium bicarbonate > no brisk effervescence in case of ethanol >brisk effervescence due to evolution of co2 in case of ethanoic acid 3)sodium metal test >H2 is given out with effervescence in case of ethanol >H2 is produced but no effervescence in case of ethanoic acid

litmus test. blue to red means ch3cooh and no change means ethanol.

Physical test: 1- oder-smell of venugar is observed. 2-litmus test- ethanoic acid turn blue litmus paper to red Chemical test: 1-sodium metal test- add a small piece of sodium metal to alcohol

Differences based on:
alkanine potassium permanganate

Ethanol reacts with sodium but not with sodium bicarbonate but ethanoic acid do
