Permanganate Ion Formula

The molecular formula of the permanganate ion is

Physical Properties

1. Molecular Weight

The molecular weight of the permanganate ion is approximately 118.93 g/mol.

2. Color

The permanganate ion is typically dark purple or violet due to its very strong absorption of light in the visible spectrum.

3. Solubility

Permanganate is highly soluble in water, where it creates a deep purple solution.

4. Oxidizing Properties

The permanganate ion is a potent oxidizing agent especially in acidic solution

5. Solubility

Potassium Permanganate is generally non-toxic and stable in normal conditions but tends to decompose when heated or in presence of some reducing agents

6. Density

The potassium permanganate compound containing the permanganate ion has a density of around 2.7 g / cm³

7. Melting and Boiling Points

Potassium permanganate melts at about 242 °C (468 °F) but does not have a definite boiling point as it decomposes before it boils.

Chemical properties

1. Strong Oxidizing Agent

MnO42− is a strong oxidizing agent. In acidic solutions, the ion can oxidize a number of substances such as iron(II) ions, hydrogen peroxide and organic compounds.

2. Redox Reactions

The ion is reduced to manganese(II) ions. The ion decolorizes to nearly colorless in an acidic solution.

3. Behavior in Neutral and Acidic Solutions

The ion is unstable in neutral or slightly acidic solutions and can be reduced by brown precipitated manganese dioxide.

4. Complexation

It can be complex with the ligands; its reactivity and solubility depend on it.

5. Decomposition

It decomposes under heat or very strong reducing agents and forms manganese oxides, and so on.

6. Acid-Base Reactions

Although permanganate itself is neither an acid nor a base it does react in acid-base mixtures. It alters the redox balance of the reaction mixture.

7. Indicator by Color-Change

Deep purple color by which the permanganate is known has made it the indicator more often applied in titrations for redox reactions, in which color change is the pointer for the endpoint.
