Detailed Solution
Formic acid behaves as reducing agent as it is oxidised to an unstable acido carbonic acid, which decomposes into CO2 and H2O.HCOOH+2HgCl2⟶ΔHg2Cl2+CO2+2HClHCOOH+2Hg2Cl2⟶CO2+2HCl+2Hg (Black) Acetic acid remains unaffected by mercuric chloride, and does not show reducing properties.
