Formic acid (systematically called methanoic acid) is the simplest
carboxylic acid.Its formula is HCOOH or CH2O2. It is an important
intermediate in chemical synthesis and occurs naturally, most
famously in the venom of bee and ant stings.
In nature, it is found in the stings and bites of many insects of
the order Hymenoptera, mainly ants. It is also a significant
combustion product resulting from alternative fueled vehicles
burning methanol (and ethanol, if contaminated with water) when
mixed with gasoline.
Properties: COLORLESS TRANSPARENT GAS WITH IRRITATING.
Application: Used in rubber flocculant, tanning agents, reducer,
chemical material, pesticide.
