Titration electrochemistry
WebAmperometric titration is the standard method for comparison of accuracy in determining residual chlorine in drinking water. FAC is determined by titration with a standard solution of As (III) (in the form of phenylarsine oxide, C 6 H 5 AsO) at a pH between 6.5 and 7.5. In this pH range, combined chlorine reacts slowly. WebIntroduction The purpose of this experiment is to perform a potentiometric titration of an acid using a glass electrode and a pH meter. The potential that develops across the glass membrane of the electrode is proportional to the concentration (more exactly, the activity) of H …
