Applications

Iron(II) sulfate heptahydrate is used as a precursor to prepare other iron compounds such as a lawn conditioner and a mordant for wool dyeing. It is actively used in the manufacture of ink including iron gall ink. As a reducing agent, it participates in the reduction of chromate in cement. It is also used in industrial water treatment plants to remove phosphate. It is also used in the gold refining process to precipitate metallic gold. Woodworkers use aqueous solutions of ferrous sulfate to color maple wood a silvery hue. It finds application in the treatment of iron chlorosis, which arises due to deficiency of iron in horticulture.

Notes

Air and moisture sensitive. Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Store in cool place. Incompatible with strong oxidizing agents.
