Experiment 7: Preparation of a Buffer

Second, you will make 100 mL of a buffer also with pH = 5, but with a higher buffering capacity, using 5 mL of a 0.5 M acetic acid solution. Although a buffer will resist a change in pH, eventually enough acid or base can be added to destroy it. The amount of acid or base needed to change the pH of a buffer is known as the "buffering capacity."

pH 7. A protein with a pI of 7 will bind more tightly to the cation column if its buffer is pH 3 rather than pH 4. The greater the electrostatic charge is, the more concentrated the sodium chloride must be to elute the target. An alternative to eluting by increasing the salt concentration is to appropriately alter the pH of the buffer. For ...
