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 … WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebHence the final molarities for both base and acid are half of their original values; 0.16 M/2 = 0.080 M (not 0.8M) and 0.20 M/2 = 0.10 M. For buffer problems involving the Henderson-Hasselbach equation, in order to find the pH of the buffer the concentrations of the acid and base, and the pKa must be known. how famous is nirvana
