Nature
white or pale yellow crystalline powder. Soluble in water. Solubility 33g/lOOmL water at 35 °c. Loss of sulfur dioxide decomposition at 360c. Soluble in dilute sulfuric acid. It is slowly oxidized to a tetravalent tin Salt in air. The acidic solution was stable.
Preparation Method
synthesis: stannous chloride is dissolved in hydrochloric acid, diluted with water, and sodium carbonate is added until the solution is alkaline. Further sulfuric acid reaction, evaporation crystallization, filtration, drying, prepared stannous sulfate.
Introduction
Sensitive to humidity. It is decomposed into tin dioxide and sulfur dioxide at about 378 ℃. It is soluble in water and dilute sulfuric acid, and the aqueous solution decomposes rapidly, and basic sulfate is precipitated at the same time. Dissolve 33g/100ml of water at 35 ℃. Decompose and lose sulfur dioxide at 360 ℃. Slowly oxidized to tetravalent tin salt in the air. The acidic solution is stable. Corrosive
Use
The electroplating industry is used as a plating solution. The printing and dyeing industry is used as a mordant. It is also used as a reagent for chemical analysis and the like.
Safety
packed in plastic woven bags lined with polyethylene plastic bags, each with a net weight of 50kg. Should be stored in a cool, dry warehouse. Pay attention to moisture-proof and sealed storage. Rain shall be prevented during transportation, and it is not allowed to be stored and mixed with edible articles. Use a gas mask when there is a lot of dust. Pay attention to protect the skin. During the production, the operator should wear protective equipment and be well ventilated.
