Test for Iron in water:
Reagents: Standard Mohr’s salt solution 1,10 phenanthroline solution Hydroxylamine hydrochloride solution
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
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.
The aqueous solutions of Sodium Bisulfite are acidic in nature. Degradation of sodium bisulfite with acid forms sulfur dioxide gas.
