Chemical properties of ferrous sulfate monohydrate

Soluble in water (1g / 1.5ml, 25 ℃ or 1g / 0.5ml boiling water). Insoluble in ethanol. It has reducibility. It is decomposed by high temperature and gives off poisonous gas. In the laboratory, it can be obtained by the reaction of copper sulfate solution with iron. It will be weathered in dry air. In humid air, it is easy to oxidize into brown yellow basic ferric sulfate which is difficult to dissolve in water. 10% aqueous solution is acidic to litmus (pH value is about 3.7). When the temperature is above 73 ℃ to 70 ℃, the molecular weight of iron is lost.
 

Function and use

It is used for making iron salt, iron oxide pigment, mordant, water purifying agent, antiseptic, disinfectant, etc;

In medicine, it can be used as anti anemia drug, local astringent and blood tonic agent, and can be used for chronic blood loss caused by hysteromyoma;

Iron fortifier as feed additive;

In agriculture, it can be used as pesticide to control wheat smut, scab of apple and pear, and rot disease of fruit tree; edible grade can be used as nutritional supplement, such as iron fortifier, fruit and vegetable coloring agent.

It can be used as fertilizer to remove moss and lichen from tree trunks. It is the raw material of magnetic iron oxide, iron oxide red and iron blue inorganic pigment, iron catalyst and polyferric sulfate.

In addition, it is also used as chromatographic analysis reagent.
