Question

MUESTION There are several cakulations that need to be done in order to prepare a specific vokurme of buier solution at a paricudar First, determine the correct A MA ratio: The p of acetic acid i 4 76,and the buffer solution needs to maintaln a pt of 4 21 The concentration of conceneration of acetik ackd (CHyCOyH) What is X concentration and pt. There is a worked example in your lab manual on p. 119 acetate (CHjCO2) should be X Simes that of h t QUESTION Thce ae several calculations that need to be done in order to peepare a specific volume of buffer solution at a particular concestration and pH. There is a worked examgle in your lab mannal os p. 11 determine the actual concentraion of A. needed to make a buffer at a particular concentration Once the correct ratio of A to HA is known, The ratio of acetate to acetic acid in a buffer is 0.177. That is, the prepare a 0 of acetate should be 0.177 limes that of the concentration of acetic acld. What is the concentration of acetate (in M) needed to 397 M bufler using acetic acid and acetate?
