Laboratory Experiments
A Dibasic Acid Titration for the Physical Chemistry Laboratory

Abstract
A physical chemistry laboratory experiment is described in which both pK, and pK2 are determined for weak dibasic acids with closely spaced acid dissociation constants. The method is acid-base titration. Data are acquired by a computer interfaced to a pH meter, however emphasis on experimental technique is retained by requiring students to manipulate a buret, read it, and manually enter the volumes into the computer. The computer is then used to ease the burden of tedious and repetitious calculations which yield the two pKa values.
