Alcaline dust
In chemistry, an alkali is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of … WebMar 12, 2024 · The Process. Alkaline hydrolysis uses water, potassium hydroxide (a common ingredient in liquid soap), relatively low heat (177 C, 350 F) versus cremation, and pressure to reduce the body of a deceased loved one to bone fragments and an inert liquid.
