WebThe following table really is the full analytical solution to a titration of a weak base (B) with a strong acid (HCl). The data (volume of titrant and pH) can be copied and pasted into a program (Excel) to plot the curve. This algorithm actually uses pH as the input and finds the right volume that produces that pH. The result is a REAL looking ... WebThe large Kb value indicates a strong base, as it means the base is largely dissociated into its ions. With the Kb value, you can calculate pKb. The lower the pKb value, the stronger the base. pKb = -log [Kb] The pH and pOH of an aqueous solution are related by the following equation: pH + pOH = 14. If either the pH or the pOH value of 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 …
