Product Description

Product Description

1. General Information
Chemical Name: Ferrous sulfate heptahydrate
Chemical Formula: FeSO4.7H2O
Appearance: It typically appears as light green, transparent, and crystal - like granules. These crystals are often large and well - formed.
Odor: Odorless.
Taste: Has a slightly astringent taste.

2. Solubility
It is highly soluble in water. When dissolved in water, the solution turns into a light green color. The solubility increases with temperature. For example, at room temperature (around 20°C), approximately 26.3 grams of ferrous sulfate heptahydrate can dissolve in 100 grams of water, and this value rises as the temperature goes up.

Application

 

Agriculture and Horticulture
Fertilizer: It is an important source of iron for plants. Iron is a crucial micronutrient for photosynthesis and enzyme activation in plants. Application of ferrous sulfate heptahydrate helps correct iron - deficiency chlorosis, where leaves turn yellow due to lack of iron. It can be applied as a soil amendment or as a foliar spray.
Soil Acidifier: In alkaline soils, it can be used to lower the soil pH. As it dissolves in soil water, it releases hydrogen ions, gradually making the soil more acidic, which is beneficial for acid - loving plants like blueberries, azaleas, and rhododendrons.
Water Treatment
Coagulant: In water treatment plants, ferrous sulfate heptahydrate is used as a coagulant. When added to water, it reacts with dissolved oxygen and hydroxide ions in water to form iron(III) hydroxide flocs. These flocs can adsorb and trap suspended particles, colloids, and some dissolved organic matter, facilitating their removal through sedimentation and filtration, thus purifying the water.
Chemical Industry
Precursor for Iron Compounds: It serves as a starting material for the synthesis of various iron - based chemicals. For instance, it can be oxidized to produce iron(III) oxide, which is widely used in pigments, magnetic materials, and as a catalyst support. It is also used in the production of iron salts for applications in the textile, leather, and dye industries.
