Buffers can be made from weak acids or base and their salts. For example, if 12.21 grams of solid sodium benzoate are dissolved in 1.00 L 0.100 M benzoic acid (C6H5COOH, pKa = 4.19) solution, a buffer with a pH of 4.19 will result: Buffers can be made from two salts that provide a conjugate acid-base pair.
How do you make a buffer solution?
Preparing a Buffer Solution
In the first method, prepare a solution with an acid and its conjugate base by dissolving the acid form of the buffer in about 60% of the volume of water required to obtain the final solution volume. Then, measure the pH of the solution using a pH probe.
What is a buffer and how is it made?
A buffer is made by mixing a large volume of a weak acid or weak base together with its conjugate. A weak acid and its conjugate base can remain in solution without neutralizing each other. The same is true for a weak base and its conjugate acid.
