Problem- Calculate the concentrations of total acetate ion for the 7 solutions below, prepared by mixing the specified volumes of .75 M acetic acid with .75 M sodium acetate, then diluting to 100.00 ml with water.
Buffer # 1 2 3 4 5 6 7
.75 M acetic acid (ml) 9.5 9.0 7.5 5.0 2.5 1.0 .5
.75 M sodium acetate (ml) .5 1.0 2.5 5.0 7.5 9.0 9.5
Mystified on the total acetate part of this problem and how to figure it out
