Acetic acid has a Ka of 1.8 times 10^{-5}. Three acetic acid/acetate buffer solutions, A, B, and C, were made using varying concentrations: 1. [acetic~acid] ten times greater than \rm [acetate], 2. [acetate] ten times greater than \rm [acetic~acid], and 3. [acetate]=[acetic~acid]. Match each buffer to the expected pH. Drag each item to the appropriate bin.
