Ammonium bifluoride is an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid and used in a number of industrial and commercial applications such as the cleaning and etching of metals and glass and the cleaning of bricks and ceramics. Do not use steel, nickel, or aluminum containers (USCG, 1999). Synonyms: Ammonium hydrogendifluoride; Ammonium difluoride; Ammonium bifluoride; Acid ammonium fluoride; Ammonium acid fluoride; and Ammonium hydrofluoride CAS Number: 1341-49-7 CAS Name: Ammonium hydrogen difluoride EC (EINECS) Number: 215-676-4 Other identifier (Please specify): GPS0051 Honeywell manufactures ammonium hydrogen difluoride for use by industry in … Hazardous Decomposition Products Hydrofluoric acid, ammonia. Hydrofluoric acid (HF) is the most effective mineral acid for breaking up strong Si–O bonds to form SiF 6 − 2 ions in acidic solution. We are a well-known company that was incorporated in the year 1995 at Dera bassi (Punjab, India). HF by itself is more effective in the digestion of silicate rock minerals than when mixed with another acid. Is ammonium fluoride acidic, or basic? It is corrosive to metals and tissue. (Fluorine) (Hydrofluoric Acid) (Sodium Fluoride) (Silicon Fluoride) (Cryolite) (Ammonium Bifluoride) GENERAL INFORMATION INDUSTRIAL HEALTH ASPECTS INDUSTRIES AND OCCUPATIONS SELECTED ABSTRACTS SELECTED REFERENCES OHIO DEPARTMENT OF HEALTH, R. H. MAREWITHf M.D. Such was the case in one skin burn due to 5 g of pure anhydrous liquid hydrofluoric acid (chilled and under pressure until the vessel burst); about 2.5% of the body surface area was estimated to have been contaminated. These fluorides are used in metal, pre metal treatment, glass etching, aluminium and in stainless steel industry. In presence of moisture will corrode glass, cement, and most metals. Hydrofluoric acid is a highly corrosive liquid and is a contact poison. Health hazards and first aid Hydrofluoric acid is very hazardous and the full extent of injuries may not be obvious for some hours. Calculate the weight% of HCl for the amount of solution you want to make up. Ammonium fluoride - hydrofluoric acid mixture Semiconductor Grade, AF 875-125, etching mixture (Honeywell 17621), CAS Number: 12125-01-8, 1341-49-7, 7732 … (Some websites give poor advice on this problem). I believe Rock is right and that this boards suffers of too much fear mongering with respect to chemistry. Trade Name Ammonium Bifluoride Technical Name Ammonium Bifluoride Scientific Name Ammonium Hydrogen Fluoride Proper Shipping Name Ammonium Hydrogen Di-fluoride, Solid Hazard Class Class 8 - … The mixture of H 2 SO 4, HF, and NH 4 F/HF contains H + from H 2 SO 4, HF, and NH 4 F/HF, SO 4 … Director ofHealth Coluni 194&* This material compiled by the Adult Hygiene Division of the Ohio Department … Belongs to the Following Reactive Group(s) Salts, Acidic; Fluoride Salts, Soluble; Potentially Incompatible Absorbents. Ammonium bifluoride solution is the white crystalline solid dissolved in water. Fahrenheit this is an effective acid. Hydrofluoric Acid , Find Complete Details about Hydrofluoric Acid,Hydrofluoric Acid,Ammonium Bifluoride,Fluorosilicic Acid from Inorganic Acids Supplier or Manufacturer-Fairsky Industrial Co., Limited While hydrofluoric acid is usually written HF, for the purpose of our discussion we will use H 2 F 2, since its molecules tend to form hydrogen bonded clusters. Owing to its low dissociation constant, HF as a neutral lipid-soluble molecule penetrates tissue more rapidly than typical mineral acids. See more. Ammonium bifluoride is less reactive and less prone to produce fumes, but perfectly capable of causing tissue damage. Similarly, hydrofluoric acid can be absorbed percutaneously to produce severe systemic poisoning. -It can also substitute and replace the ammonium bifluoride; the advantage is that the ammonium polyfluoride is liquid has no problem of aging, ammonium bifluoride over time always cakes, as a solid acid salt.-It is far less aggressive than the HF. The citric and nitric blends with hydrofluoric acid or ammonium bifluoride will remove these Class III rouges more quickly but will definitely etch the surface wher-ever the base metal is subjected to the derouging fluid. Jianyang Xinyi Trading Corp.Ltd.Fujian,China - China supplier of HYDROFLUORIC ACID, AMMONIUM FLUORIDE, AMMONIUM BIFLUORIDE, Electronic grade HF The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. In industrial textile processing or laundries, it is used for pH adjustment. AMMONIUM BIFLUORIDE reacts violently with bases. You need to take the same precautions with ammonium bifluoride as you do with hydrofluoric acid. It should be handled with extreme care, beyond that accorded to other mineral acids. Hydrofluoric acid can also be generated from bifluoride salts when mixed with an acid, for example ammonium bifluoride with sulfuric acid. Bifluoride definition, an acid salt of hydrofluoric acid containing the group HF2-, as ammonium bifluoride, NH4HF2. About 50 parts, by weight, of ammonium bifluoride, about 12 parts of sodium bifluoride, about 33 parts of corn starch, about 5 parts of 35 magnesium fluosilicate, and about 1 part of sulphonated naphthalene are thoroughly mixed together to a dry powdered product, which is mixed with hydrofluoric acid solution, for use, the strength of the acid being desirably 20-40 40 per cent. Please tell me if the relative safety of ammonium bifluoride, hydrofluoric acid and hydrochloric acid can be represented by their individual pH. Results from three separate single endpoint titrations are used to calculate the results. Ka for hydrofluoric acid = 6.4 x 10-5 Kb for ammonia = 1.8x10-5 Alibaba.com offers 750 ammonium bifluoride mix with hydrofluoric acid products. Flammable hydrogen gas may collect in enclosed spaces.
