The pH to H+ formula that represents this relation is: \small \rm {pH = -\log ( [H^+])} pH = −log( [H+]) The solution is acidic if its pH is less than 7. If the pH is higher, the solution is basic (also referred to as alkaline).

WebThe pH is a measure of the concentration of hydrogen ions, the acidity or alkalinity of a solution. The pH-scale is normally between 0 and 14. Aqueous solutions at 25 ° C with a … 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 …
WebFeb 4, 2024 · pH is a measure of hydrogen ion concentration, [H+], in an aqueous (water) solution. The pH scale ranges from 0 to 14.
