Sodium sulfate prevents formation of scum by the molten glass during refining, and also fluxes the glass. The compound also helps in removing imperfections during the blowing and casting processes.
Sigma-Aldrich offers a number of Sodium sulfate products. View information & documentation regarding Sodium sulfate, including CAS, MSDS & more.
A. Ferrous sulfate won't drop either Pt or Pd along with the gold. About the only contaminate in the gold will be a little iron from the ferrous sulfate. If you have Pt or Pd, it is common to first use ferrous sulfate. Then re-dissolve in aqua regia and drop a second time with a sulfite such as sodium metabisulfite, sodium sulfite, or SO2.
Soda ash is the trade name for sodium carbonate, a chemical refined from the mineral trona or sodium-carbonate-bearing brines (both referred to as "natural soda ash") or manufactured from one of several chemical processes (referred to as "synthetic soda ash"). It is an essential raw material in glass, chemicals, detergents, and other important industrial products.
Mar 22, 2013· Sodium sulfate is widely used as a fining agent in high-tonnage glass technology. Since the conditions for redox glassmaking and Fe 2+ ↔Fe 3+ equilibrium displacement are formed under the influence of sulfate, the glassmaking process and glass quality largely depend on the quality and particulars of sulfate interaction with a reducing agent. The reactions and stages of sulfate action .

Detergents (e.g. sodium lauryl sulfate, sodium dodecylbenzenesulfonate) – normally synthetic from propene, can have complex hydrocarbon structures (e.g. benzene rings). They are less likely to react with ions in hard water, and so do not form a 'soap scum'.
Sodium sulfate is the sodium salt of sulfuric acid.With an annual production of 6 million tonnes, it is one of the world's major commodity chemicals. Anhydrous, it is a white crystalline solid of formula Na 2 SO 4; the decahydrate Na 2 SO 4 ·10H 2 O has been known as Glauber's salt or, historically, sal mirabilis since the 17th century..

In these reactions, dissolved solids are not reduced because a solution reaction product (sodium sulfate or sodium chloride) is formed. Warm Lime Softening. The warm lime softening process operates in the temperature range of 120-140°F (49-60°C). The solubilities of calcium, magnesium, and silica are reduced by increased temperature.

Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.
