Introduction

Soluble in water, almost insoluble in ethanol, lose carbon dioxide at about 50 ℃, and all heat becomes sodium carbonate at 100 ℃. It decomposes rapidly in weak acid, and its aqueous solution begins to decompose carbon dioxide and sodium carbonate at 20°C, and completely decomposes at the boiling point. Dissolved in 10 parts of water at 25 ℃ and 12 parts of water at about 18 ℃. The unstirred solution made of cold water 8.3 the pH value of 0.1mol/L aqueous solution freshly prepared with phenolphthalein test paper. Low toxicity, half lethal dose (rat, oral) 4420mg/kg.
