Analysis
Appearance : White crystalline solid (Orthorhombic crystals)
NH4HF2 : 98.76%*
(NH4)2SO4 : 0.05%
(NH4)2SiF6 :0.20%
Moisture :0.59%
Solubility in water : 60.2 g at 20°C and 156.4g at 60°C per 100ml of water
Solubility in HCl : 10% (w/v) sample is soluble in 15% (w/w) of HCl at 25°C
*Assay: Weigh accurately about 1.0gm of Ammonium bi fluoride sample. Dissolve it in 100ml distilled water. Titrate with about 1N NaOH. Use Phenolphthalein as indicator. End point is Colourless to Pink.
% acidity as HF = A / B
1st calculate Consumption of NaOH, B.R. X Normality of NaOH X 0.02 X 100 = A
Then Divided the result with " Weight of the sample " = B
%NH4HF= %acidityasHFx57 / 20
Ammonium bifluoride is a white crystal salt chemically when ammonium bifluoride comes in contact with water resulting with the formation of HF. It is used to brighten aluminum and other metals.

Non-Flammable
Safe Plant Handling
Low Odor
Provides corrosion protection in the liquid and the vapor phase
When used in hydrostatic testing the product provides protection in liquids below, above and at the liquid levels. Protection of recessed and hard to reach areas. Complicated valves and the interior surfaces of piping and equipment, which are often difficult or impossible to reach, are protected with true Vapor Corrosion Inhibitor action. Can be applied for hydrotest solution, metalworking fluids, coatings, adhesives and water treatment formulations.
Risk of serious damage to eyes. In case of contact with eyes, rinse immediately with plenty of water & seek medical advice. Wear suitable gloves and eye / face protection
