Ka chemistry - Acid Dissociation Constant (Ka), Relating Ka and pKa

WebIn chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction known as dissociation in the context of acid–base reactions. WebThe weakest acid is the acid that dissociates least, that is, the concentration of ions in solution will be least, therefore [H +][anion] will be smallest, so given all the solutions are the same concentration of monoprotic acid, the acid with the lowest concentration of ions will have the lowest value of K a. The acid with the smallest K a ... WebThis scale is known as pH scale. pH of acids and bases is defined as the negative logarithm (with base 10) of activity of hydrogen ion (H + ).
