Unformatted text preview: Chem 123 Lab Report Darian Arman Lab ID: A5105 Jan. 28, 2008 Abstract: The pH of a phosphate buffer solution was determined, after adding NaOH or HCl, using a pH meter, to simulate the affects of acidosis and alkalosis in blood. Many more mL of HCl were needed to lower the pH by one than NaOH to raise the pH by one. Introduction: In the medical field there are many cases of alkalosis, which may lead to death if not treated. In order to lower the blood pH (between 7.35 and 7.45), a method of treatment is injecting concentrated hydrochloric acid. The amount of hydrochloric acid to be injected is determined from the total base excess. Using concentrated hydrochloric acid to treat alkalosis is safe, effective and leads to rapid correction (Kwun 1983). In this experiment, the amount of HCl or NaOH was determined, to find out how many mL of each is required to change the buffer solution by one pH unit. The research has been conducted to show that when blood has alkalosis, a strong acid (HCl) is required lower the pH to the desired...
