- The student was supposed to measure the pH of a 0.1 M hydrochloric acid solution. For this purpose, he used a pH-meter and obtained the following results: 0.90, 0.93, 1.04, 1.02. Present the appropriate graphic and statistical elaboration of the performed analysis and confirm whether the applied pH-meter worked properly.The partition coefficient of ammonia between water and chloroform is wanted to be determined. The necessary quantities of ingredients are taken into the separation funnel, and the extraction process is applied. At the end of the extraction process, 5 mL portions of each of the water and chloroform phases are titrated with 0.1 M HCI in the presence of methyl orange indicator. If the volumes spent at the turning points are 7.2 and 5.1 mL, respectively, calculate the KSU, KLOROFORM (Dispersion coefficient) value.What are method blanks and method detection limit used in analytical chemistry?
