Is calcium sulfite a precipitate?

Calcium sulfite is a sulfite with good reducing properties. It can be used not only as a bleaching agent, but also as a filler for calcium plastic boards. If it encounters strong acid, it will easily dissolve, thus releasing toxic sulfur dioxide gas. The main source of calcium sulfite is stones in nature, and it has great industrial value. So is calcium sulfite a precipitate?

First, is calcium sulfite a precipitate? Yes, it is a precipitate. Calcium sulfite is insoluble in water, with a solubility of 0.0043 g/100 mL. Calcium sulfite (CaSO3), a sulfite, has reducing properties and can be used as a bleaching agent. Chemical properties and uses: Decomposes in acid, releasing toxic sulfur dioxide gas. It is used to make calcium plastic materials, and is also used as a bleaching and dechlorination agent for cellulose products, a food preservative, a fermentation bactericide, etc. Preparation method: Use calcium chloride and sodium sulfite to carry out double decomposition reaction in solution, filter, isolate from air and dry to obtain anhydrous CaSO3 solid. (Equation: Na2SO3+CaCl2=CaSO3↓+2NaCl). It can also be obtained by chemical reaction of sulfur dioxide and calcium hydroxide. (Chemical reaction equation

Formula: SO2+Ca(OH)2=CaSO3↓+H2O). Second, it will not fall off when boiled at 100 degrees. It has strong air permeability, allowing water molecules to pass freely. It has high adsorption capacity and can purify deeply and over a large area, killing various pathogens in the water and inhibiting the growth and reproduction of bacteria and microorganisms. This product not only adsorbs organic matter, but also has a strong adsorption effect on toxic and harmful metal ions and bacteria and viruses. It is the preferred product for water purification production and tap water dechlorination purification equipment manufacturers, filling the gap in domestic and foreign infinite antibacterial and mildew prevention. It is widely used in high-end water treatment systems in Japan, South Korea, Malaysia, Taiwan and other Southeast Asian countries and regions. Due to these characteristics, it can be used as an analytical reagent, and is also used to make calcium plastic materials, as a bleaching and dechlorination agent for cellulose products, a food preservative, a fermentation bactericide, etc. It is also used as a filter medium to treat various industrial sewage, industrial water, urban tap water, pure water, and soft water.

Is calcium sulfite a precipitate? Properties: CaSO3·2H2O White crystalline powder. Density: 1.595. Loses crystal water at 100°C. Decomposes at 650℃. Slightly soluble in water. Carbonates and sulfites have similar properties. Barium sulfite is insoluble in water but easily soluble in acid.
