CHEMICAL AND PHYSICAL PROPERTIES

Physical Description A solution made from lime, sulfur, and water containing calcium polysulfide, free sulfur, and calcium thiosulfate; [Hawley] Orange liquid with odor of rotten eggs; [ICSC] Deep red orange liquid; [MSDSonline]
Color/Form Deep orange liquid
Odor Unpleasant smell of hydrogen sulfide
Solubility Soluble in water
Density 1.28 @ 15.6 °C
Decomposition Decomposed by carbon dioxide, acids, and soluble salts of metals which form insoluble sulfides; sulfur, hydrogen sulfide and the metal sulfide being formed.
pH IT IS SLIGHTLY ALKALINE DUE TO HYDROLYSIS, WHICH IS ACCELERATED BY DILUTION
Other Experimental Properties It decomp by carbon dioxide, by acids and by the sol salts of those metals that form insol sulfides, leading to precipitation of sulfur and the formation of hydrogen sulfide or insol metal sulfides.
Chemical Classes Pesticides -> Fungicides
