Chemical Properties

slightly grey-purple adhering crystals or powder

Uses

Medicine, analytical chemistry, textile dyeing (mordant).

Uses

Ammonium ferric sulfate dodecahydrate may be used as a catalyst to synthesize:

• Isoamyl acetate from acetic acid and isoamyl alcohol.
• 2-Amino-5-(5-nitro-2-thienyl)-1,3,4-thiadiazole from 5-nitrothiophene-2-carboxaldehyde thiosemicarbazone via oxidative cyclization.

Definition

Ferric alum: One of the alums,K₂SO₄.Fe₂(SO₄)₃.24H₂O, in which thealuminium ion Al³⁺ is replaced bythe iron(III) (ferric) ion Fe³⁺.

Purification Methods

Crystallise it from aqueous ethanol.
