A buffer is a combination of substances whose presence in an aqueous solution will keep a solution at neutral pH (7.00). convert a weak acid to a strong acid. maintain the pH of a given solution. maintain a constant salt concentration within the solution.

What is a buffered solution? 1. Solutions that contain both a weak acid and it's conjugate base, or a weak base and it's conjugate acid. While most solutions change pH slowly when either acid or base is added, a buffer solution changes pH very quickly by neutralizing the added acid or added base. 2. Solutions that contain both a weak acid and it's conjugate base, or a weak base and it's conjugate acid. While most solutions change pH rapidly when either acid or base is added, a buffer solution resists pH change by neutralizing the added acid or added base. 3. Solutions that contain both a strong acid and strong base. While most solutions change pH rapidly when either acid or base is added, a buffer solution resists pH change by neutralizing the added acid or added base.

In general, a buffer is a solution containing a weak acid and its conjugate base. The amount of strong base or acid that must be added to one liter of a buffer in order to change its pH by one unit is an expression of buffer capacity.

A buffer solution: changes readily in pH upon addition of acid or base. consists of a mixture of a weak acid and its conjugate base. has a pH equal to the pKa of the weak acid that's in solution. consists of a weak acid in aqueous solution. resists changes in pH upon addition of large amounts of acid or base.
