Barium may cause constipation or impacted stool after the swallowing test if it isn't completely cleared from your body. You can manage constipation by drinking plenty of fluids and eating foods high in fiber to help the rest of the barium leave your body.

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
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.

Functional Properties of Acacia Gum
Acacia Gum / Gum Arabic readily dissolves in water to give clear solutions ranging in colour from very pale yellow to orange·brown and with a pH of - 4.5. The highly branched structure of Acacia senega/gum gives rise to compact molecules with a relatively small hydrodynamic volume and as a consequence gum solutions become viscous only at high concentrations. 30% gum Acacia solutions have a lower viscosity than 1 % xanthan gum and sodium carboxymethylcellulose at low shear rates. In addition.
Acacia Gum is Newtonian in behaviour with viscosity being shear rate independent.The other major functional characteristic of gum Arabic is its ability to act as an emulsifier for essential oils and flavours. It is now known that the protein·rich high molecular mass component adsorbs preferentially onto the surface of the oil droplets. It is envisaged that the hydrophobic polypeptide chains adsorb and anchor the molecules to the surface while the carbohydrate blocks inhibit flocculation and coalescence through electrostatic and steric repulsions. Since only part of the gum is involved in the emulsification process, the concentration required to produce an emulsion is much higher than for pure proteins. For example, in order to produce a 20% orange oil emulsion then Acacia concentrations of - 12% are required. Once formed the emulsions can remain stable for long periods of time.
