Ph of a strong alkali

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 … WebpH: A scale ranging from 0 to 14 that measures the degree of how acidic or basic a solution is. pH and pOH: pH + pOH = 14. pH equation for calculating a strong acid: pH = -log ( H+ H +) pH ...
