Phase relationships in the sodium sulphate – sulphuric acid and sodium pyrosulphate – water systemsPhase diagrams for the Na2SO4-H2SO4 and Na2S2O7-H2O systems were determined from the melting points of samples of various compositions. High-purity materials were used and the melting points were ...
Incompatible with finely powdered metals,arsenic, carbon, phosphorus, sulphur, metal cyanides,thiocyanates, impure manganese dioxide, sulphuric acid.May decompose on exposure to light, air or moisture.Heat and shock sensitive. 2.6 StorageTemp Store at +5°C to +30°C....
Sodium sulphate may be produced industrially by the reaction of magnesium sulphate with sodium chloride in solution followed by crystallization, or by the reaction of concentrated sulphuric acid with solid sodium chloride. The latter method was used in the Leblanc process for the production of alkali...
