Manganese chloride: Versatile industrial partner with potential
Manganese chloride, also known as MnCl₂, is an important chemical compound with a variety of industrial applications. As part of the group of transition metal compounds, manganese chloride possesses unique properties that make it a valuable material in modern industry. In this blog post, we will take a closer look at the key characteristics, applications, and safety aspects of manganese chloride.
Properties of manganese chloride
Manganese chloride is a crystalline, greenish-white salt that is soluble in water. It has the molecular formula MnCl₂ and a molecular weight of 125.84 g/mol. The melting point is 650 °C, and the boiling point is 1190 °C. Manganese chloride crystallizes in a tetragonal crystal system.
The most important physical properties of manganese chloride include:
- High solubility in water (approximately 71 g/100 ml at 20 °C)
- Good solubility in ethanol and other polar organic solvents
- Paramagnetic behavior due to unpaired electrons in the Mn²⁺ ion
- Greenish-white color of crystals and solutions
These properties make manganese chloride a versatile material for industrial use.
Industrial applications of manganese chloride
Manganese chloride is used in a wide range of industries. Some of the most important application areas are:
