Measurement of Ph

Whether pH is being used to test a sample against a legal requirementor specification; as part of an analytical method; for monitoring andcontrolling a reaction; as a process control in the chemical industry;or for the environmental monitoring of waste and effluents, it isimportant that all pH measurements are carried out in a logical andconsistent manner, paying careful attention to experimentalprocedures, in order to obtain reliable results. This guide providesscientists with the knowledge of how to do just that, first byoutlining the principles of pH measurement and buffer solutions. pHmeters and electrodes are then discussed, including selection criteriaand the care of electrodes. Finally, sections on making pHmeasurements and uncertainty are followed by a set of practicalexercises."Measurement of pH" is one of the "Practical Laboratory SkillsTraining Guides", a series that aims to make achieving best practiceeasy. These invaluable manuals will enable both experienced andinexperienced staff to get the essential basics of any experimentright simply by following the clear and easy to use instructionsprovided. The guides are written by experienced scientists andinclude minimal theory, plenty of practical exercises in order toassess competence, and trouble shooting information.
