A buffer solution is a solution of, usually, a weak acid and its conjugate base or, less commonly, a weak base and its conjugate acid a buffer solution resists changes in the concentrations of the hydronium ion and hydroxide ion (and therefore ph) when the solution is diluted or when small amounts of an acid or base are added to it. Example of calculating the ph of a buffer solution using the henderson-hasselbalch equation, including the ph of the buffer solution after adding some naoh. Lab protocols protocols solution preparation resuspension buffer (solution i) for isolation of plasmid by alkaline lysis method resuspension buffer. Example of calculating the ph of solution that is 100 m acetic acid and 100 m sodium acetate using ice table another example of calculating ph of a soluti. Acetate buffers are used in which base in table 3 in chapter 143 relative strengths of acids and bases is most appropriate for preparation of a buffer solution.
3 the preparation of buffers at desired ph objectives: c make the solution and check the ph of a portion of your buffer solution using the ph meter. Preparation of buffer aim: to prepare the buffer at required ph ph meter and measures the ph of the prepared solution this gives citrate buffer at.
