Hydrazine Test Reagent TK - 17

Size:

Color:

Product Short Description: Reagent of Hydrazine Test Kit powder
Product Technical Specification:

Add 2 micro spoon full of Reagent TK-17. Mix well upto provider dissolves Completely. Wait for 10 minutes.

Remarks:

Before Sampling all PRECAUTION should be taken :::

Toxic effects of Hydrazine ( which is collected in sample ) is a severe skin and mucous membrane irritant in humans; in animals.In humans, the vapor is immediately irritating to the nose and throat and causes dizziness and nausea; itching, burning, and swelling of the eyes develop over a period of several hours. Severe exposures of the eyes to the vapors causes temporary blindness lasting for about 24 hours. Recurrent exposure to hydrazine hydrate has been reported to cause contact dermatitis of the hands without systemic intoxication. In humans, hydrazine is absorbed through the skin, by inhalation, and orally; systemic effects include weight loss, weakness, vomiting, excited behavior, and convulsions; the chief histologic findings are fatty degeneration of the liver and nephritis.

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.

Product Technical Specification:

Product Specification:

Product Number:  M8266
CAS Number: 7786-30-3
MDL: MFCD00011106
Formula: Cl2Mg
Formula Weight: 95.21 g/mol

Appearance (Color) White
May contain gray or black specks  
Appearance (Form) Powder
Water Insolubles < 0.5 %
Water (by Karl Fischer) < 3.0 %
Titration with EDTA Anhydrous > 98 %
Recommended Retest Period  4 Years  
 
Remarks:

It is formulated using quality tested chemicals and advance technology. Magnesium Chloride flakes are flat in shape to help decrease bounce and scatter, allowing the material to stay in centralized locations. These flakes are odorless and can be used in addition to sodium chloride to help initiate the brining process, and can also be mixed with sand to help increase penetration of ice and snow.
