An organic compound with molecular formula $C_{2}H_{4}O_{2}$ produces brisk effervescence on addition of sodium carbonate / bicarbonate. Answer the following :
a) Identify the organic compound.
b) Write the chemical equation for the above reaction.
c) Name the gas evolved.
d) How will you test the gas evolved ?
e) List two important uses of the above compound.
a)Since the carbon compound gives effervescence with sodium carbonate bicarbonate it could be an acid. Further $C_{2}H_{4}O_{2}$is corresponding to general molecular formula of carboxylic acids is C_{n}H_{2n}O_{2}, it is Ethanoic acid.
b)
c)The gas evolved is C{{O}_{2}}.
d)I will pass this gas through lime water. It will convert to milky indicating the evolved gas convert to milky indicating the evolved gas is C{{O}_{2}}.
e)1) It is used as preservative in pickles.
2) It is used in saponification.
