	Formic acid - LoveToKnow 1911
		Its nitrile (prussic acid) has an acid character, a property not possessed by the nitriles of the other members of the series; and, by the abstraction of the elements of water from the acid,.
		The free acid, when heated with concentrated sulphuric acid, is decomposed into water and pure carbon monoxide; when heated with nitric acid, it is oxidized first to oxalic acid and finally to carbon dioxide.
		The esters of the acid may be obtained by distilling a mixture of the sodium or potassium salts and the corresponding alcohol with hydrochloric or sulphuric acids.

	Formic Acid
		Formic acid is a colorless, fuming liquid with a highly pungent, penetrating odor.
		Acute, overexposure to formic acid causes corrosion of the skin, eyes, and mucous membrane of the mouth, throat, and esophagus and may be associated with complications such as cardiovascular collapse and ischemic damage to the heart, liver and kidneys, swelling of the airway, and respiratory distress.
		Before a worker is placed in a job with a potential for exposure to formic acid, a licensed health care professional should evaluate and document the worker's baseline health status with thorough medical, environmental, and occupational histories, a physical examination, and physiologic and laboratory tests appropriate for the anticipated occupational risks.

	Silver Conservation
		For this reason, treatment in a formic acid electrolyte is often used for silver that has the original surface preserved in the corrosion layer.
		During electrolysis, the reduced silver corrosion layers regenerated on the surface of the metal in formic acid are left in granular or particulated layers, which are physically weak and tend to separate from the metallic core.
		Because the corrosion layers are particulated, silver that is reduced in formic acid tends to be dark, brittle, and rigid.

		B. Neutralize 1 ml of formic acid with sodium hydroxide TS and add 2 drops of the acid in excess; then add about 1 ml of ferric chloride TS: a deep reddish orange colour results which turns to yellowish orange on the addition of mineral acids.
		C. Place 2 ml of formic acid in a test-tube, add 5 ml of sulfuric acid and test the gas evolved with a lighted splinter: a blue flame characteristic of carbon monoxide is produced.
		Formic acid (or formate) is apparently more toxic than other fatty acids, possibly owing to its enzyme-inhibiting activity.

		Working with formic acid as a mite control active ingredient is very different from nerve disruptors like synthetic pyrethroids (Apistan®) and organophosphates (Checkmite™).
		Mite-Away II technology releases enough formic acid over three weeks to be an effective dose, charging the colony environment, but not enough to damage the colony health.
		Likewise, when bees breathe in the formic acid vapor, the tracheal mites are exposed to formic acid and die.

		Formic acid gel is a slow release formulation of formic acid in a plastic pouch for control of tracheal mite and suppression of varroa mite in colonies of honeybees.
		The formic acid gel pack must be removed from the hive at least four weeks (28 days) before the beginning of surplus honey flow to prevent contamination of marketable honey.
		If all the formic acid has been evaporated from the packet so that only dry powder remains, the used gel pack can be disposed of in a sanitary landfill, or by incineration, or if allowed by State and local authorites, by burning.

		In Europe, formic acid is given, not only by slow diffusion methods, but often as rapid volatilisation.
		For all treatments involving formic acid, a 65% acid concentration was used, even if the Swiss Beekeeping Research Center recommends 85% when applications are administered from the bottom of the hive.
		Formic acid treatments were applied at intervals of 4 to 7 days, except for the last flash when it was decided to wait for good weather and more importantly for more of the last brood to be hatched.
