Causes of Leg Pain Video. The purpose of this article is to emphasize that there are many spinal conditions that may cause leg pain, foot pain, and other lower extremity symptoms. Most successful treatments are based upon having an accurate anatomic diagnosis for the basis of a specific pain syndrome.
A permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO 4 â).Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent. The ion has tetrahedral geometry. H+ + MnO 4 â + 5 e â â Mn 2+ + 4 H 2 O. In a strongly basic solution, permanganate(VII) is reduced to the green +6 oxidation state of the manganate ion, MnO 4 2â .
To get the molecular formula or ionic formula in this case, you need to know the valencies of the elements constituting that compound. For instance here, Magnesium has valency 2, Oxygen has valency 2, so $\ce{MgO}$ is the formula for Magnesium Oxide. For example, Sodium Oxide, Sodium has valency 1, Oxygen has valency 2, so $\ce{Na_2O}$ is the formula for Sodium Oxide. Iron (III) Oxide becomes: $\ce{Fe_2O_3}$ (Iron valency = 3; Oxygen valency = 2).
