Microscale techniques have been developed or rediscovered in the past decade for general (1), organic (2), and inorganic (3) chemistry lab experiments, but few microscale analytical (4 ) experiments have been developed. The analytical chemistry experiments that are presented in textbooks (5-8) still describe the use of macroscale analytical glassware and large sample sizes that have been standard since the start of analytical chemistry. We present a technique for microscale pH titrations that use 1-5 mL of analyte and a similar volume of titrant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
