The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Ammonium permanganate is a strong oxidizer, owing to its permanganate anion, and it is a moderately strong explosive, owing to the combination of oxidizer permanganate anion and reducing ammonium cation. Dry ammonium permanganate can detonate by heat, shock, or friction, and it may explode at temperatures above 140 °F (60 °C). [1]
A permanganate (/ p ər ˈ m æ ŋ ɡ ə n eɪ t, p ɜːr-/) [1] is a chemical compound with the manganate(VII) ion, MnO − 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]
Rubidium permanganate is soluble in water with a solubility of 6.03 g/L at 7 °C, [3] 10.6 g/L at 19 °C, [2] and 46.8 g/L at 60 °C. [6] Its crystal structure is orthorhombic , [ 1 ] the same as caesium permanganate , ammonium permanganate and potassium permanganate .

Apples. The original source of sweetness for many of the early settlers in the United States, the sugar from an apple comes with a healthy dose of fiber.
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 ]
