buffer) is a solution that contains a conjugate acid-base pair–that is when the acid undergoes a reaction, it turns into its conjugate base; and when the base undergoes a reaction it turns into its ...

Note: the NaCl will not be pH 7, but rather approximately pH 5 due to dissolved CO2in the water. A procedure to prepare the buffers to eliminate the CO2 follows, but was found to be relatively ...

Prepare a buffer solution by accurately calculating and measuring the required amounts of both the acid and the base components. Use a burette set-up to administer precise quantities of acid and base ...

Use a weak acid such as acetic acid and a weak base such as ammonia and after a few times the demonstration will no longer change colors. This variation provides a demonstration for the effect of ...
