Usage and Dosage:
1. Industrially: ferrous sulphate heptahydrate 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 sulphate 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 sulphate can also be used to stain concete and some limestones and sandstones a yellowish rust color.
4. Water Treatment: Ferrous sulphate has been applied for the purification of water by flocculation and for phosphate removal in municipal and industrial sewage treatment plants to prevent eutrophication of surface water bodies.

Product feature
Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous.
Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature,
