Iron (II) Sulfate

What is Iron (II) Sulfate?

Molecular Formula (Iron (II) Sulfate): FeSO ₄

Molecular Weight: 151.91 g/mol

Chemical Name: Iron (II) Sulfate

CAS Number: 7720-78-7

Iron (II) Sulfate is a chemical compound formed by the presence of the +2 valent Fe ⁺² ion and the -2 charged SO ₄ ^-2 sulfate ion.

Ferrous Sulfate is a chemical found in crystal form with a greenish color and a yellow-brown appearance.

Other Names are as follows;

• Ferrous Sulfate
• Iron (II) Sulfate
• Iron 2 Sulfate
• Monohydrate Form
• 7720-78-7
• Anhydrous Form
• Fe (II) Sulfate
• Ferrous Sulfate
• Sulfuric Acid Iron 2 Salt

How is Iron (II) Sulfate Produced?

Ferrous Sulfate production is obtained by treating iron with sulfuric acid. The chemical that emerges due to the effect of sulfuric acid on iron is iron sulfate.

What are the Physical and Chemical Properties?

Physically, it has a green form or a yellow-brown appearance. It has hygroscopic properties.

The melting point is 64 °C.

Boiling Point: No information available.

Its density is 3.56 g/cm³.

In terms of solubility, it has good solubility in water.

In terms of stability, the outer surface in humid environments becomes covered with brown-looking Ferric sulfate.

Heating Ferrous Sulfate emits sulfur oxide gas, which is a toxic fume.

What are the Application Areas of Iron (II) Sulfate?

• It is a chemical used to clean rust and dirt formed on equipment used in the mining sector. In this way, the equipment becomes longer-lasting and more useful.
• In cement production, it is added to provide both cost advantages and to give the cement good strength. In this way, high strength is achieved at a low cost.
• Iron deficiency in plants leads to a decrease in chlorophyll synthesis. In some soils, the pH is particularly high. High pH generally occurs in calcareous soils. By lowering the pH of calcareous soils, the uptake of the iron element by the plant is ensured. Iron deficiency in plants is corrected with the addition of Ferrous Sulfate and Sulfur.
• The iron element is a very important mineral for plants. Chlorophyll synthesis occurs in enzymes found in plant cells. Thanks to chlorophyll synthesis, color pigments are formed in plants. However, in some plants, chlorophyll synthesis does not work very well. This may be due to iron deficiency. Therefore, agricultural pesticides containing this chemical are produced to eliminate iron deficiency in plants. As a result of iron deficiency in plants, cell division decreases and growth is inhibited.
• In the winter months, grass becomes weak against frost. For this purpose, by using Ferrous Sulfate, the grass is ensured to have a greener appearance and to be hard and vivid against freezing cold. The only difference from iron sulfate used to inhibit weeds in agriculture is that it is used at a lower dosage.
• Used for inhibiting algae. In this way, the spread of algae is prevented.
• Organic acids found in fruits and vegetables cause discoloration. Iron sulfate-based fertilizers are used to prevent discoloration.
• Legume type plants oxidize and darken in alkaline conditions. Fertilizers containing this chemical are used on legumes to take advantage of its reducing properties. In this way, color protection is provided in legumes.
• It is used in the production of some chemicals in the chemical industry. These are; chemicals such as sulfur dioxide and sulfuric acid.
• The anhydrous form is used in products manufactured for use as an iron supplement in non-medicinal nutritional supplements.
• In case of high amounts of Chromium in cement, FeSO4.7H2O is used to reduce this chromium. It has a higher reducing capacity than Sodium Metabisulfite.
• It is used as a very effective plant nutrient in agricultural fertilizers where Glycolic Acid is the solvent. The most important feature here is that it meets the iron needs of plants.

What are the Factors Affecting Prices?

The price changes depending on the prices of the chemicals and ores used. As iron and sulfuric acid prices increase, prices will increase.

The price of iron sulfate will increase with the expansion of agricultural businesses in a country. Because the use of this chemical for agricultural purposes has a large area.

As companies that sell Iron (II) Sulfate increase their stocks, prices show short-term decreases.

With the establishment of a new production facility, prices will experience a short-term decrease. However, in the event of a new application area emerging, prices will move upwards.
