Gum Arabic Powder BR Grade Reagent
Cas Number:9000-01-5
Formula: NA
Molar Mass:NA
EC Number:232-519-5
Physicochemical properties:
Transparent particles or white-yellowish powder. It is completely soluble in 2 times the weight of water and the solubility in 100g saturated solution is: 37g at 25°C, 38g at 50°C, 40g at 90°C, aqueous solution is acidic to litmus, it is soluble in glycerin and propylene glycol and insoluble in ethanol. The relative density is 1.35-1.49 (the dry product is heavier at 100 °C). Irritating
Usage:
Analytical chemistry is used as a protective colloid. Some colorimetric and turbidity analyses are used to prevent settling of the precipitate. Silver is assayed for aluminum, bismuth, arsenic, antimony, magnesium and selenium. Adhesive. Emulsifier.
Packing:
500g/25kg
