A simple buffer system might be a 0.2 M solution of sodium acetate; the conjugate pair here is acetic acid HAc and its conjugate base, the acetate ion Ac . The idea is that this conjugate pair "pool" will be available to gobble up any small (? 10 3 M ) addition of H+ or OH that may result from other processes going on in the solution. how to make a dovetail marker 18/05/2009 · What weight ratio of acetic acid to sodium acetate should be used to prepare a buffer of pH 4.55?
