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. The correct order of increasing acidity is:

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. The correct order of increasing acidity is:
