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 ...

Students will use what they have learned to complete a Buffer Challenge. Figure 1. Reference molecule for definition of Brønsted-Lowry acids and bases. Water behaves as both an acid and a base. When ...

Strong base is added to three different buffers and water and the effect on pH is observed.

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 ...
