Procedure

The titrant solution (0.1N perchloric acid/dioxane) was prepared by adding 9 ml of perchloric acid to 1000 ml dioxane, and was stored in a brown bottle. A stock solution of potassium hydrogen phthalate ("KHP") was prepared by dissolving 2.5452 g KHP (dried at 120° C. overnight) in 250 ml glacial acetic acid. A 10 ml aliquot of this solution was placed in a 500 ml beaker with an additional 50 ml of glacial acetic acid. Titrations were carried out with continuous stirring, and the millivoltage was monitored with a combination electrode connected to a pH meter.
