Potassium nitrate (KNO 3), known historically as saltpeter or the mineral niter, is a common salt with multiple uses. It has been known since antiquity; an early appearance in the chemical literature ...

The process sees hot and metal-rich fluids interact with surrounding rocks, causing chemical and mineralogical ... is shown by the presence of potassium-rich minerals, such as K-feldspar and ...

Researchers have developed a hydrogel-based strain sensor that measures blood potassium from a single drop of serum in two ...

We saw there lithium, then sodium and then potassium, but you didn't see rubidium, caesium and francium. Gethin: Francium. That's not an element that you hear a lot of. Miss Armit: No, it's the ...

element. "Potassium is a much more abundant material, and potassium-ion batteries have a lot of potential as an alternative method of storing and delivering large amounts electricity. Adopting ...

We considered our alternatives, which would involve a chemical reaction of some sort. Although dissolving potassium carbonate (K 2 CO 3) in water is an exothermic process, it isn’t a chemical ...

Group 1 elements react with moist air. They are stored in oil to stop air and water vapour coming into contact with them. Moist air reacts with potassium to form potassium oxide. This creates a ...
