Specification

The Ferrous ammonium sulfate hexahydrate, with the CAS registry number 7783-85-9, is also known as Diammonium iron disulfate hexahydrate. It belongs to the product category of Metal Sulfate. Its EINECS number is 233-151-8. This chemical's molecular formula is (NH₄)₂^.Fe^.(SO₄)₂^.6(H₂O) and molecular weight is 392.14. What's more, its systematic name is Ammonium iron(2+) sulfate hydrate (2:1:2:6). This chemical should be sealed and stored in a cool and dry place. Moreover, it should be protected from oxides. It is used as analytical reagents. It is also used as polymerization catalysts.

Physical properties of Ferrous ammonium sulfate hexahydrate are: (1)#H bond acceptors: 16; (2)#H bond donors: 22; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 232.66 Å².

Preparation: dissolve ferrisulphas and ammonium sulfate in a small amount of water, and then heat to 60-70 °C and pour into porcelain. Use a small amount of sulfuric acid to acidize and stir continously to cool (temperature not more than 60 °C). Filter out crystallization after standing, then wash with 50% ethanol, and dry in a cold place until crystallization does not stick to the glass rod, and the analytically pure products are made.

FeSO₄ + (NH₄)₂SO₄ + 6H₂O = (NH₄)₂Fe(SO₄)₂·6H₂O

When you are using this chemical, please be cautious about it as the following:
It is irritating to eyes, respiratory system and skin. In case of contact with eyes, you should rinse immediately with plenty of water and seek medical advice. When using it, you need to wear suitable protective clothing, gloves and eye/face protection.

You can still convert the following datas into molecular structure:
