10.0 Abnormal Behaviour of Formic Acid
The behaviour of formic acid is different from other carboxylic acid due to presence of aldehydic group.
Reaction with
1. Tollen’s reagents: formic acid behaves as a reducing agent and reduces Tollen’s reagent or Felhing solution. But others acid fail to do so.

Red ppt.
2. Reaction with $HgC{l_2}$ : Formic acid forms white ppt of $H{g_2}C{l_2}$ with $HgC{l_2}$ which is converted to Grey ppt of mercury.
