Calcium permanganate
Calcium Permanganate[edit | edit source]
Calcium permanganate is an inorganic compound with the chemical formula Ca(MnO₄)₂. It is a salt consisting of calcium cations (Ca²⁺) and permanganate anions (MnO₄⁻). This compound is known for its strong oxidizing properties and is used in various applications, including water treatment and as a disinfectant.
Properties[edit | edit source]
Calcium permanganate is a purple crystalline solid that is highly soluble in water. It is a powerful oxidizing agent, similar to other permanganates such as Potassium permanganate. The compound decomposes upon heating, releasing oxygen and leaving behind manganese dioxide (MnO₂) and calcium oxide (CaO).
Chemical Formula[edit | edit source]
Ca(MnO₄)₂
Molar Mass[edit | edit source]
277.95 g/mol
Appearance[edit | edit source]
Purple crystalline solid
Solubility[edit | edit source]
Highly soluble in water
Preparation[edit | edit source]
Calcium permanganate can be prepared by the reaction of Potassium permanganate with calcium chloride in an aqueous solution. The reaction is as follows:
2 KMnO₄ + CaCl₂ → Ca(MnO₄)₂ + 2 KCl
This reaction results in the formation of calcium permanganate and potassium chloride as a byproduct.
Uses[edit | edit source]
Calcium permanganate is used in various applications due to its oxidizing properties:
- Water Treatment: It is used to remove iron and manganese from water, as well as to control taste and odor.
- Disinfectant: It serves as a disinfectant in water treatment processes.
- Oxidizing Agent: It is used in chemical synthesis as an oxidizing agent.
Safety and Handling[edit | edit source]
Calcium permanganate is a strong oxidizer and should be handled with care. It can cause fires if it comes into contact with combustible materials. Proper protective equipment, such as gloves and goggles, should be worn when handling this compound.
