Formic acid is miscible with water and most polar organic solvents,
and somewhat soluble in hydrocarbons. In hydrocarbons and in the
vapor phase it consists of hydrogen-bonded dimers rather than
individual molecules. Owing to its tendency to hydrogen-bond,
gaseous formic acid does not obey the ideal gas law. Solid formic
acid (two polymorphs) consists of an effectively endless network of
hydrogen-bonded formic acid molecules. This relatively complicated
compound also forms a low-boiling azeotrope with water (22.4%) and
liquid formic acid also tends to supercool.
