sodium bicarbonate(1) Characteristics: White powder or tiny crystalls, nodorousand salty,easily soluble in water, insolublein alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposd to moist air. (2) Specification: The Total Alkalinity Content(NaHCO3): 99.0-100.5% Loss on Dring:----------------- 0.20% max. PH Value(10g/1) Solution:--- 8.6 max. Arsentic Content: --------------0.0001% max. Heavy Metal Content:---------- 0.0005 max. Ammonium Salt: -----------------pass Clearness: ------------------------pass Particle Size: 20mesh, 40mesh, 60mesh, 80mesh, 100mesh, 140mesh (3) Uses: Used as food fermentation, detergent ingredient, carbondoxide foamer, pharmacy, leather, ore milling and metallurgy, detergent for wool, exting uisher and metal heat-treating, fiber and rubber industry, etc. (4) Advantage: i. Particle size from 20mesh to 140mesh; ii. Bigger particle size than other suppliers(the larggest particle is 20mesh), not easy to be caking and good free-flowing crystalline powder; iii. Higher whiteness 94% min.
