Product Description
The water of crystallization endows it with unique physical properties.Appearance and PropertiesColor: Pure crystals are light green. The crystal particles are translucent, resembling broken jade or jadeite, so it is commonly known as "green vitriol" or "black vitriol".State: At room temperature, it exists as crystals, is easily soluble in water, and its aqueous solution is light green. Due to the hydrolysis of Fe², it shows weak acidity.Chemical Formula and StructureThe chemical formula is FeSO4·7H2O, meaning that each ferrous sulfate molecule combines with seven water molecules of crystallization to form monoclinic crystals.In the crystal structure, Fe² ions are bonded to water molecules and sulfate ions through coordination and ionic bonds.
Ferrous sulfate is a crystal with a pale green luster. In the form of heptahydrate, it is like crushed emerald particles, exuding a clear metallic texture in the sunlight. Its chemical properties are like those of a sensitive "color - changer". When exposed to air, the pale green color will gradually be tinged with a rusty yellow - brown color over time - that is the mark of the oxidation of ferrous ions, as if telling a silent battle with oxygen. After dissolving in water, it will tint the clear liquid into a delicate light green, just like the newly sprouted willow buds in spring soaking in water. When a strong alkali solution is added, the instantly formed white ferrous hydroxide precipitate will "change its face" at an astonishing speed. Under the action of oxygen, it quickly puts on a reddish - brown coat, staging a shocking chemical magic show.

Application
After ferrous sulfate heptahydrate dissolves in water, due to the hydrolysis of Fe², it shows acidity, which can lower the soil pH value, make iron exist in a free state, and improve soil fertility (such as improving saline - alkali land). Agriculture and HorticultureApplication of Iron Fertilizer: It is a commonly used fertilizer for preventing and controlling iron deficiency chlorosis in plants (such as citrus, grapes, etc.). It can be applied by burying in the soil or spraying on the leaves to supplement iron elements and promote the synthesis of chlorophyll.Soil Improvement: It is used to adjust the pH value of alkaline soil, making iron elements exist in an absorbable ionic state and improving the utilization rate of nutrients by plants.
Core raw material of iron fertilizerPrevention and treatment of iron deficiency chlorosis: When plants (such as citrus, grapes, tea trees, vegetables) are deficient in iron, their leaves lose their green color and turn yellow. Ferrous sulfate heptahydrate can be applied to the soil or sprayed on the leaves to provide absorbable Fe², promote the synthesis of chlorophyll, and restore the green color of the leaves.Usage examples: For fruit trees, a 0.2% - 0.5% aqueous solution can be sprayed on the leaves, or it can be mixed with organic fertilizer and buried; for potted plants, a 0.1% solution is commonly used to irrigate the roots once every 2 - 3 weeks. Soil acid - base adjustmentIn alkaline soils, iron elements are likely to form insoluble Fe(OH)3, which cannot be absorbed by plants.
Catalysts and Reducing Agents: Used as a reducing agent in organic synthesis reactions, or as a catalyst support (such as in the synthesis industry)Industrial and Chemical Production
Pigments and Dyes: Used for preparing iron-based pigments, such as iron green (Prussian blue type), iron red (Fe2O3, obtained by oxidizing and calcining FeSO4), and can also be used as coloring raw materials for inks and coatings.
Battery Materials: As an iron source for preparing cathode materials of lithium-ion batteries (such as lithium iron phosphate LiFePO4), it plays a role in the new energy field.
Packaging & Shipping
Packing: Package in 25/50/1000kg bag, also accpet customer OEM packing. Pack in sealed plastic bags, plastic drums or iron drums lined with plastic bags to avoid contact with air and moisture; For industrial - grade products, woven bags lined with polyethylene film bags can be used, with a net weight of 25kg or 50kg per bag. Ensure that the bags are tightly sealed.
