*Three reaction mixtures(20%, 40% and 60%) were placed on a stir plate for 1 hour. | |||

*Three drops of bromothymol blue were added to each reaction mixture before titrating with sodium bicarbonate solution prepared [[User:Moira_M._Esson/Notebook/CHEM-581/2012/11/09|2012/11/09]] | |||
*PHP solution had not completely dissolved. Standardization of sodium bicarbonate must still be performed. In order to facilitate the dissolving of PHP, 20.424g of PHP will be remeasured, dried and divided three equivalent portions. These equivalent portions will be added to three separate beakers and deionized H<sub>2</sub>O will be added to the beakers to create a 1M solution. | |||
