- 2. Chemical Properties Chemical Chemical Properties of Na2SO4 Salt
- Na2SO4 chemical is sustainable
It is not oxidized at normal temperature, but under high temperature catalyzed conditions, it can act with carbon (reduced).
Of (2)SO (4) + 2C → Of (2)S + 2CO (2)
- Na2SO4 chemicals are basic Sodium sulfate can react with sulfuric acid to form sodium bisulfate salts:
Na(2)SO(4) + H(2)SO(4) ⇌ 2 NaHSO(4)
- + Note: With different concentrations and temperatures we will have different equalization coefficients.
- Na2SO4 chemical has ion exchange properties
- Sodium sulfate salts are typical ionic salts, containing Na (+) and SO (4) (2 −) ions. The presence of sulfate in solution is readily recognized by the formation of insoluble sulfates when treating these solutions with Ba (2 +) or Pb (2 +) salts:
Na (2) SO (4) + BaCl (2) → 2 NaCl + BaSO (4) (Precipitation)
- 3. Application
- 1. Na2SO4 chemical is applied in glass making
- Sodium sulfate salt is used as one of the main compounds in glass production. Sodium sulfate can prevent the formation of residue by molten glass during refining. Sodium sulfate can also make glass surface. Sodium sulfate acts as a smoothing agent in a molten glass. Sodium Sulfate will remove small air bubbles and prevent the foaming process of the molten glass while refining.
- 2. Na2SO4 chemical is applied in detergent industry
- Sodium Sulfate salt is used as a filler in the detergent industry especially laundry detergent. However, because of its environmental harm, it has been greatly restricted.
- 3. Na2SO4 chemical is applied in pulp production
- Sodium sulphate salt participates in the Kraft cycle as an intermediate. Wood scales are heated with sodium sulphate to form sodium sulfic, breaking the cellulose bonds in the wood; So the wood scales become softer and easier to form wood powder.
- 4. Na2SO4 chemical is applied in textile industry
Sodium sulphate salt is an ideal compound for textile dyeing, as it does not corrode the steel vessels as well as having cathodes on the fabric fibers, so the dye easily seeps through the fabric fibers more effectively and evenly.
- 5. Na2SO4 chemical is applied in medical
Sodium sulfate is one of the compounds we use as laxatives. Sodium sulfate salts in medical treatments use it as a chemical compound to cleanse the intestines before an application of certain procedures.
- 4. Storage
Store in a cool, dry place. Limit direct contact to the skin.
