Unit 14 Acids and Bases
Notes 14.2
Strong acids—this equilibrium lies far to the right (products). A strong acid produces a weak conjugate base. CB is much
+
weaker than water. Water wins the H
competion.
Weak acids—the equilibrium lies far to the left (reactants). Weak acid has a CB that is a much stronger base than water.
+
Water does not win the H
competition CB does. A weak acid yields a relatively strong CB.
Relative strengths of conjugate acid-base pairs.
Diprotic acids—more than one hydrogen to give.
Oxyacid—acidic hydrogen is attached to an oxygen.
Organic acids –COOH group
Monoprotic acids—one hydrogen to donate
Polyprotic acids—more than one hydrogen to donate.
