HClO4(aq)+NaOH(aq)⟶H2O(l)+NaClO4(aq). For example,hydrogen chloride (HCl) dissolves in water to form hydrochloric acid. Since we know that HClO3 is a strong acid, we can identify -ClO3 as its conjugate base, and can conclude that it is likely a weak conjugate base at that. In that case, we normally make a mixture of a weak acid plus a weak base, and that weak base might either just be a weak base like ammonia, or it might be a salt with the conjugate base of our weak acid. Example 13. 2 Acid Strength 7. salt/acid or conjugate base/acid .
