Formaldehyde works to fixate the tissue of the deceased. This is the characteristic that also makes concentrated formaldehyde hazardous when not handled using appropriate personal protective equipment. The carbon atom in formaldehyde, CH 2 O, carries a slight positive charge due to the high electronegativity of the oxygen double bonded with the ...
