A powerful base that is useful in organic … Sulfuric acid - diluted solution. It is an alkali metal hydride. Solubility: dec in cold and hot water; insol CS 2, ether, benzene. This reaction was discovered by the same scientist who identified potassium … Potassium hydride is extremely flammable upon exposure to water… Sulfuric acid react with potassium hydroxide to produce potassium sulfate and water. Our channel. Potassium is the seventh most abundant element on earth. 1. It is a white solid, although commercial samples appear gray. Section 3 – Potential Hazards. Potassium hydride, whose formula is represented as KH, is an inorganic substance that is classified as an alkali metal hydride because it is formed by directly combining molecular hydrogen with potassium through the following reaction: H 2 + 2K → 2KH . Potassium hydride is a highly moisture sensitive reagent that reacts violently with air and/or water. Upon reaction with water, it can ignite. Purification: commercial KH dispersion is made by reduction of metallic potassium… Form Supplied in: as a dispersion in mineral oil, 20–35% by weight. As with other alkali metals, potassium decomposes in water with the evolution of hydrogen because of its reacts violently with water… Thermodynamic properties of substances The … Potassium hydride, KH, is the inorganic compound of potassium and hydride.
