Dissociation of acid and base
WebThe acid–base strength of a molecule depends strongly on its structure. The weaker the A–H or B–H+ bond, the more likely it is to dissociate to form an H + ion. In addition, any factor that stabilizes the lone pair on the conjugate base favors the dissociation of H +, making the conjugate acid a stronger acid. http://ion.chem.usu.edu/~scheiner/LundellChemistry/practiceproblems/ch11_practiceproblems.pdf

WebSep 18, 2024 · NH4OH is an exception since it contains both ionic and covalent bonds, but as a general rule, acids contain ionic bonds whereas bases contain covalent bonds. Thus, acids ionize and bases dissociate. In covalent compounds also, there is a distinction: polar and non polar. Polar compounds also have an ionic character, so they also dissociate.
