Permanganic acid (or manganic(VII) acid) is the inorganic compound with the formula H MnO 4 and various hydrates. [3] This strong oxoacid has been isolated as its dihydrate. It is the conjugate acid of permanganate salts. It is the subject of few publications and its characterization as well as its uses are very limited.
Food psychology is the psychological study of how people choose the food they eat (food choice), along with food and eating behaviors. [1] Food psychology is an applied psychology , using existing psychological methods and findings to understand food choice and eating behaviors. [ 2 ]
4, the conjugate base of permanganic acid. Because the manganese atom has a +7 oxidation state, the permanganate(VII) ion is a strong oxidising agent. The ion is a transition metal ion with a tetrahedral structure. [2] Permanganate solutions are purple in colour and are stable in neutral or slightly alkaline media. The exact chemical reaction ...
A food storage calculator can be used to help determine how much of these staple foods a person would need to store in order to sustain life for one full year. In addition to storing the basic food items many people choose to supplement their food storage with frozen or preserved garden-grown fruits and vegetables and freeze-dried or canned ...

The purplish-black color of solid potassium permanganate, and the intensely pink to purple color of its solutions, is caused by its permanganate anion, which gets its color from a strong charge-transfer absorption band caused by excitation of electrons from oxo ligand orbitals to empty orbitals of the manganese(VII) center.
Permanganic acid can be prepared by the reaction of dilute sulfuric acid with a solution barium permanganate, the insoluble barium sulfate byproduct being removed by filtering: [3] Ba(MnO 4) 2 + H 2 SO 4 → 2 HMnO 4 + BaSO 4. The sulfuric acid used must be dilute; reactions of permanganates with concentrated sulfuric acid yield the anhydride ...
Low-acid foods, such as vegetables and meats, require pressure canning. Food preserved by canning or bottling is at immediate risk of spoilage once the can or bottle has been opened. Lack of quality control in the canning process may allow ingress of water or micro-organisms.
