Acetic acid is added to the solution of sodium carbonate the gas evolved does not turn purple colour of KMnO_(4) but turns lime water milky forming a compound (M) which becomes soluble by passing the same gas in excess forming another compound (N). But same obserbation is not obtained with boric acid. Purple colour of KMnO_(4) has not changed because:

1.	Acetic acid is added to the solution of sodium carbonate the gas evolved does not turn purple colour of KMnO_(4) but turns lime water milky forming a compound (M) which becomes soluble by passing the same gas in excess forming another compound (N). But same obserbation is not obtained with boric acid. Purple colour of KMnO_(4) has not changed because:
Answer» the gas has no oxidising property since central atom is in minimum oxidation state the gas has no reducingproperty since the central atom is in MAXIMUM oxidation state the gas has no precipitattion characteristics the gas PRECIPITATES `CaCO_(3)` from line water Solution :`Na_(2)CO_(3) OVERSET(ACOH)rarr CO_(2) overset(Ca(OH)_(2))rarr underset((M))(CaCO_(3)darr) overset(CO_(2))underset(H_(2)O)rarr underset((N))(Ca(HCO_(3))_(2))`
