WebFeb 2, 2024 · The equilibrium constant for a dissolution reaction, called the solubility product ( Ksp ), is a measure of the solubility of a compound. Whereas solubility is usually expressed in terms of mass of solute per 100 mL of solvent, Ksp is defined in terms of the molar concentrations of the component ions. In contrast, the ion product ( Q) describes ... WebThe table lists the K a values and the strength of each acid and base. Strong acids are listed at the top left-hand corner of the table and have Ka values >1. Acids with a K a value less than one are considered weak …

Web0.6. The Taft equation is a linear free energy relationship (LFER) used in physical organic chemistry in the study of reaction mechanisms and in the development of quantitative structure–activity relationships for organic compounds. It was developed by Robert W. Taft in 1952 [2] [3] [4] as a modification to the Hammett equation. [5]
