AMMONIUM Bifluoride Crystal

Size:

Color:

Product Short Description: If the acid used in the working mixture of hydrofluoric acid (45%), it would take 1.55 times more than if we use a dry ammonium bifluoride.
Product Technical Specification:


CAS Number‎: ‎1341-49-7
UN number‎: ‎1727
Boiling point‎: ‎240 °C (464 °F; 513 K)
EC Number‎: ‎215-676-4
Molecular Weight: 57.04 g/mol
Molecular Formula: NH4HF2

Ammonium bifluoride [NH4.HF2]

Melting point :124.6°C (Sublimes at higher temperature) 
Boiling point : 239.5°C
When dissolved in water, cooling takes place. Material is Hygroscopic at 50% humidity.

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

Remarks:

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.
