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 Na₂CO₃or a bicarbonate like NaHCO_3^.......

ethanoic acid reacts to give to give CO₂and no reaction takes place in case of ethanol.

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

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

SAME CASE WITH NaHCO₃

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.

CH3-C=O-OH

alcohol -saturated carbon compound.

CH3-CH2-OH

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 test.....here ethanoic acid and ethanol both have double covalent bonds..!

Divesha answered this

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..

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.
