Potassium readily loses the single electron in its outer valence, causing it to react very energetically to substances that strongly attract electrons. Potassium is a silver colored metal that tarnishes rapidly when exposed to air because of the oxygen and water vapor.Know More
When exposed to air, potassium turns into potassium oxide, and under certain conditions, burns forming potassium superoxide. It has extremely energetic reactions with water, forming potassium hydroxide and hydrogen gas, which burns with a lilac-colored flame.
Potassium reacts very strongly with halogen gases and acids, forming potassium salts and, in the case of acids, helium gas. It reacts readily with a large majority non-metallic elements, including common elements such as sulfur, phosphorus and nitrogen. These reactions are often extremely energetic or even explosive. In order to be safely stored, potassium must be immersed in a highly inert substance like oil and kept in a suitable container.
Potassium is an important element for most organisms and forms a very wide variety of common compounds. It is also one of the more common trace elements in the Earth's crust. It is crucial in intracellular mechanisms, where it works opposite sodium to control the movement of water across membranes. Several edible plants have high levels of potassium compounds, including bananas and spinach.Learn more about Chemistry
The chemical formula for potassium hydroxide is K(OH). This compound is formed by one atom of potassium and one molecule of hydroxide, which is formed by one atom each of oxygen and hydrogen.Full Answer >
Sodium chloride is composed of approximately 60 percent chloride and 40 percent sodium elements. Commonly known as table salt, it is a white-colored or transparent water-soluble crystalline solid with the chemical symbol NaCl.Full Answer >
Bananas possess marked nutritional value. They supply a large quantity of carbohydrates to the human body and an unripe banana has more starch than sugars. The fiber extracted from the pseudostem and peduncle parts of banana plants constitutes cellulose, hemicellulose, pectin and lignin.Full Answer >
Baking soda, otherwise known as sodium bicarbonate, has the chemical properties of not being flammable, being easily decomposed by acids, starting to decompose in water solution at approximately 20 degrees Celsius and an increasing alkalinity in solution as it is heated or stirred. Baking soda is used for cleaning and cooking and is effective at putting out certain types of fires.Full Answer >
