Gas produced when potassium reacts with water
WebWhat gas is produced when potassium reacts with water? hydrogen gas. When potassium is added to water, the metal melts and floats. It moves around very quickly on the surface of the water. The metal self-ignites, which also ignites the hydrogen gas. This results in sparks and a lilac flame. WebAug 15, 2024 · Metal oxides, peroxides, and superoxides dissolve in water actually react with water to form basic solutions. Oxygen also forms covalent oxides with non-metals, that react with water to form acidic solutions. Oxygen does not react with fluorine or noble gases. Exceptions to all of these trends are discussed below. Reactions with Hydrogen
