Permanganate(VII) is a strong oxidizer, and similar to perchlorate. It is therefore in common use in qualitative analysis that involves redox reactions ( permanganometry ). According to theory, permanganate is strong enough to oxidize water, but this does not actually happen to any extent.
Potassium permanganate is an inorganic compound with the chemical formula KMnO 4. It is a purplish-black crystalline salt, ... The chemical reaction, in which ...
Potassium permanganate (KMnO 4) is a dark violet colored powder. Its reaction with glycerol (commonly known as glycerin or glycerine) (C 3 H 5 (OH) 3) is highly exothermic, resulting rapidly in a flame, along with the formation of carbon dioxide and water vapour: 14 KMnO 4 (s) + 4 C 3 H 5 (OH) 3 (l) → 7 K 2 CO 3 (s) + 7 Mn 2 O 3 (s) + 5 CO 2 ...
Another advantage that sodium permanganate has over potassium permanganate is that sodium permanganate, due to its high solubility, can be transported above ground as a liquid, decreasing the risk of exposure to granules or skin contact with the substance. [3] The primary redox reactions for permanganate are given by the equations: MnO − 4 ...
The chemical chameleon reaction shows the process in reverse, by reducing violet potassium permanganate first to green potassium manganate and eventually to brown manganese dioxide: [1] [2] [5] KMnO 4 (violet) → K 2 MnO 4 (green) → MnO 2 (brown/yellow suspension) Blue potassium hypomanganate may also form as an intermediate. [6]
Permanganometry is one of the techniques used in chemical quantitative analysis. It is a redox titration that involves the use of permanganates to measure the amount of analyte present in unknown chemical samples. [1]
Potassium permanganate, KMnO 4, is a widely used, versatile and powerful oxidising agent. Permanganic acid solutions are unstable, and gradually decompose into manganese dioxide, oxygen, and water, with initially formed manganese dioxide catalyzing further decomposition. [6] Decomposition is accelerated by heat, light, and acids.
Barium permanganate is a chemical compound, with the formula Ba(MnO 4) 2. [2] It forms violet to brown crystals that are sparingly soluble in water. Preparation
