Sodium picosulfate of appearance and properties: monoclinic system, short columnar crystal, the assembly is dense clumps or crusty, colorless, transparent, sometimes with yellow or green, soluble in water. White, odorless, has a bitter taste of crystallization or powder, has the water absorbability. Appearance is colorless, transparent, the crystallization of big or small crystal granularity. Sodium sulfate is oxyacid acid alkali and salt.
Sodium sulfate is sulfate and sodium ions generated salt and sodium sulfate in water and its aqueous solution is neutral, soluble in glycerin and not soluble in ethanol. Inorganic compounds, sodium sulfate hydrate and ten glauber's salt, high purity, fine grain anhydride called sodium sulphate, exposed to the air suction easily generate 10 hydrated sodium sulfate, sodium ten hydration commonly known as glauber's salt. Sodium sulphate, white, odourless, has a bitter taste of crystallization or powder, has the water absorbability. Appearance is colorless, transparent, the crystallization of big or small crystal granularity. Mainly used in the manufacture of sodium silicate, glass, enamel, pulp, refrigeration mixture, detergent, desiccant, dye diluent, analysis of chemical reagents, pharmaceuticals, feed, etc. At 241 ℃ sodium sulfate crystallization will shift into six square. In organic synthesis laboratory sodium sulfate is one of the most commonly used post-processing desiccant.
