Question:

Dentists give a liquid for mouth washing at the time of removing bad tooth. Is it of Potassium Permanganate?

* What's the purpose of using this solution?

*Can I have more details on the ingredients of this solution please?


Answers:

Potassium permanganate is the chemical compound KMnO4. In this salt, manganese is in the +7 oxidation state. The salt is also known as "permanganate of potash" and "Condy's crystals". The permanganate ion is a strong oxidizing agent. It dissolves in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals.[1] It has a sweet taste and is odourless. [2]

Standard enthalpy of formation is ΔfH°solid = -813.4 kJ.mol-1 and standard molar entropy is S°solid = 171.7 J.K-1.mol-1.

Its crystal structure is orthorhombic with constants: a = 9.105, b = 5.720, c = 7.425 (.10-1 nm). Distance between Mn and O atoms in tetrahedral anions is 162.9 pm.

Sodium permanganate has essentially the same properties and use as potassium permanganate and can be used as its direct substitute.

Potassium permanganate is used as an oxidizing agent in many different kinds of chemical reactions in a laboratory and in industry. It is also used as a disinfectant and in deodorizers.
