Potassium permanganate is more common. Potassium iodide can reduce potassium permanganate to potassium manganate. It can also be made by reacting hot potassium permanganate with potassium hydroxide. This makes oxygen and potassium manganate. Uses. Potassium manganate does not have many uses. It is mainly made when potassium permanganate is made.potassium hydroxide, chemical compound with formula KOH. Pure potassium hydroxide forms white, deliquescent crystals. For commercial and laboratory use it is usually in the form of white pellets. A strong base, it dissolves readily in water, giving off much heat and forming a strongly alkaline, caustic solution (see acids and bases acids and bases,

Alkenes react with potassium manganate(VII) solution in the cold. The colour change depends on whether the potassium manganate(VII) is used under acidic or alkaline conditions. If the potassium manganate(VII) solution is acidified with dilute sulphuric acid, the purple solution becomes colourless. In contrast when potassium permanganate is thermally decomposed a mixture of K^MnO^ and K^Mn04 was found . DCP analysis indicated 7.31 wt% sodium and TGA 13 wt% water to give the formula Na^MnO^-vH^O where x=035 and y =0.78 assuming a Mn:0 ratio of 1:2. The microprobe showed the presence of manganese, oxygen and sodium. Determination of iron using potassium dichromate: Redox indicators Theory As an oxidant, dichromate has some advantages over permanganate, but, as it is less powerful, its use is much more limited. It is obtainable in a state of high purity and can be used as a primary standard. Solutions of dichromate in water are stable indefinitely.
Potassium permanganate spontaneously reduces in an basic solution to green-coloured potassium manganate, where manganese is in the +6 oxidation state. Biomedical uses Dilute solutions are used as a treatment for canker sores (ulcers) (0.25%), disinfectant for the hands (about 1%) and treatment for mild pompholyx dermatitis or fungal infections ...Calcium permanganate is an oxidizing agent and chemical compound with the chemical formula Ca(MnO 4) 2.It consists of the metal calcium and two permanganate ions. It is noncombustible, but, being a strong oxidizing agent, it will accelerate the burning of combustible material. A permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO − 4). Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry. Permanganate solutions are purple in color and are stable in neutral or slightly alkaline media. The ... Potassium Permanganate is also known as permanganate of potash or Condy’s crystals. It is a chemical compound with the chemical formula of KMnO4. Learn more about other names of potassium permanganate are chameleon mineral, Condy’s crystals, permanganate of potash, and hypermangan.

1) An ionic bond is best described as A) the sharing of electrons. B) the transfer of electrons from one atom to another. C) the attraction that holds the atoms together in a polyatomic ion. Further oxidation of D gives E, C 7 H 6 O 2, which can also be produced from A by vigorous oxidation with alkaline potassium manganate(VII) solution. The reaction of B with potassium cyanide under suitable conditions gives F, C 8 H 7 N, which in turn can be reduced to G, C 8 H 11 N.

May 20, 2012 · The first person to have calculated the number of molecules in any mass of substance was Josef Loschmidt, (1821-1895), an Austrian high school teacher, who in 1865, using the new Kinetic Molecular Theory (KMT) calculated the number of molecules in one cubic centimeter of gaseous substance under ordinary conditions of temperature of pressure, to be somewhere around 2.6 x 10 19 molecules. In 1659, German chemist J.R. Glauber, fused a mixture of the mineral pyrolusite and potassium carbonate to obtain a material that, when dissolved in water, gave a green solution potassium manganate (K2MnO4) which slowly changed colour to violet to form potassium permanganate and then finally red.
