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 Crystal Glass Etching Acidsample. 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:
Crystal Glass Etching Acid is a white crystal salt chemically when Crystal Acid comes in contact with water resulting with the formation of HF. It is used to brighten aluminum and other metals.
Product Short Description: Silicone oils and other siloxane polymers consists of alternating silicon and oxygen atoms. Silicone oils are comprised of linear repeating chains of silicon and oxygen, with each silicon atom also having two carbon-based substituents.
