• pH 

Magnesium Sulphate Monohydrate usually ranges between 5.5 and 8.5 depending on the concentration. 
 

Physical Properties
 

• Appearance

It appears in White crystalline powder from fine powders to large granules according to the requirements of users and the production process. 

• Density

The density of magnesium sulfate monohydrate is 2.66 g/cm³. It is required for consideration in storage and transport. 

• Melting Point

 Magnesium Sulphate Monohydrate loses its water at 150°C (decomposes) and converts to anhydrous magnesium sulfate(MgSO4). 

• Hygroscopicity

 It tends to absorb moisture from the air which requires a moisture controller like drying agents or humidity regulation. 

• Thermal Properties

Magnesium Sulphate Monohydrate has low thermal conductivity. 

Industrial and Agricultural Applications

Industrial Application

• Construction

It’s used in cement to improve the strength, and durable structure, and to control the setting time of cement. 

• Paper Industry 

It’s used in the production of paper, to process the pulp and improves the overall quality of paper. 

• Food Industry

It’s widely used in the food industry as a fermenting agent, enhances flavor, maintains texture, provides stability, and acts as a nutrient supplement. 

• Water Treatment

It’s used to treat water by removing calcium and magnesium ions. It allows the softening of the hard water and prevents scale formation in pipes and boilers. 

• Leather Industry

It is widely accepted in the leather tanning process to provide stability and quality to manufactured products. 

Agriculture Application
 

• Healthy plant growth 

Plants also require magnesium to enhance the growth of plants. So, Magnesium Sulphate Monohydrate helps in deficiencies of magnesium in soil. It allows for improved crop production, enhanced chlorophyll production, and helps to improve the health of plants. 

• Formulation of fertilizers

It’s used to formulate fertilizers for synthesis and enzyme function in plants. It balances the supply of nutrients, increases the intake of nutrients, and helps to improve the overall health of plants. 

• Nutrient for hydroponic system

In the case of the hydroponic system, it’s used as a nutrient solution for the optimal requirement of magnesium and sulfur. It improves the quality of crops and enhances the growth condition. 

• Direct spray for rapid nutrients

It works well for the quick correction of nutrient deficiency, improves the color of the leaf, and fast photosynthesis in leaves. It’s a quick solution with water and directly sprayed on leaves to boost the quantity of nutrients in plants. 

Health and Medical Uses

• Magnesium Sulphate Monohydrate acts as a bronchodilator in case of an asthma attack. It provides relaxation to bronchial muscles and improves airflow. 
• It helps to relieve different types of pain like chronic and neuropathic pain to provide comfort to patients. 
• It’s used in bathing to provide soothing effects on sore muscles and inflammation. It reduces the pain in muscles and makes it provide a more effective and easy solution to relieve pain.
