Applications
1. Industrially: ferrous sulfate is mainly used as a precursor to other iron compounds. It is a reducing agent, for the reduction of chromate in cement.
2. Nutritional supplement: together with other iron compounds, ferrous sulfate is used to fortify foods and treat iron-deficiency anemia. Constipation is a frequent and uncomfortable side effect associated with the administration of oral supplements. Stool softeners often are prescribed to prevent constipation.
3. Colorant: ferrous sulfate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
