Properties

Inorganics sodium thiosulfate, also named sodium sulfite, baking soda and Haibo (from its alias sodium hyposulfate), molecular formula: Na2S2O3 · 5H2O. It is a common thiosulfate, colorless and transparent monoclinic crystal with a density of 1.667 g / cm3. The melting point at standard atmospheric pressure is 48 ℃. Sodium thiosulfate is easily soluble in water and reacts with strong acid to produce sulfur and sulfur dioxide
