Chapter 16 Relating pKa and pKb Review I Constants | Periodic Table Ar Learning Goal: To understand the relation between the strength of an acid or a base and its pKa and pKb values. The degree to which a weak acid dissociates in solution is given by its acid-ionization constant, Ka. For the generic weak acid, HA, HA(aq) A (aq) H (aq) and the acid-ionization constant is given by a HA Similarly, the degree to which a weak base reacts...

A Review | Constants | Periodic Table Percent ionization can be used to quantify the extent of ionization of an acid in solution and is defined by the following formula for the acid HA: A certain weak acid, HA, has a Ka value of 3.4x10-7. HA) ionized x 100% Percent ionization = - Part A Percent ionization increases with increasing Ka. Strong acids, for which Ka is very large, ionize completely (100%). For weak acids, the percent ionization...
