Hexahydrate ferric chloride is synthesized from iron or iron oxides reacting with hydrochloric acid.
Tetrahydrate ferrous chloride is derived from steel pickling waste liquid or synthesized from potassium chloride and iron powder.
Both compounds have distinct applications, with hexahydrate focusing on high oxidation scenarios and tetrahydrate on reducing environments.
สอบถาม:
What are the main differences between hexahydrate ferric chloride and tetrahydrate ferrous chloride?
Hexahydrate ferric chloride is used in high oxidation scenarios like water treatment and electronics, while tetrahydrate ferrous chloride is ideal for reducing environments such as wastewater decolorization and magnetic material production.
How is hexahydrate ferric chloride produced?
Hexahydrate ferric chloride is produced by reacting iron or iron oxides with hydrochloric acid to form a solution, which is then crystallized.
What precautions are needed for tetrahydrate ferrous chloride storage?
Tetrahydrate ferrous chloride must be stored with nitrogen protection or vacuum packaging to prevent oxidation and maintain product stability.
