実験手順

This JP publication also describes the formation of “thiosulfuric acid magnesium, MgS2O3.6H2O” by the reaction of sodium thiosulfate with Magnesium chloride and also from Magnesium Sulfite with sulfur and excess Mg(OH)2. Magnesium sulfite is first produced from magnesium hydroxide, water and sulfur dioxide. The solubility of Mg(OH) is 0.004% in water at 100° C. There is no mention of sulfite consistency or concentration of the product.
