Weak Acids and Bases as Buffers

Postby Rhiannon Imbeah 2I » Tue Jul 26, 2016 10:24 pm

Hello,
Just a question about the concept of weak acids and bases. How can a weak acid or base act as a buffer if the do not fully dissociate? Wouldn't it suffice to use a strong acid or base?

Thank you

A compound is a good buffer if it is present in both forms (neutral and ionized) to act as an acid or as a base.

A strong acid (or base) is the opposite of this as they are completely in their ionized state.
