15) There may be some interest in attacking the chemistry involved here through the cyanoallenes, Ph2C=C=C(CN)Ph or PhCH=C=C(CN)Ph, but these are unknown. (16) (a) M. Rosenblum, N.
Simplification of apparatus is possible in titrations of relatively larger amounts of calcium. Manual titrations can be carried out using a regular pH meter as the indicator. Sharp end points are obtained if 10_2M or stronger titrants are used. A color indicator is less suitable because strict requirements are imposed on the stoichiometry of the titrant because the pH of the sample is not allowed to change significantly during the titration.
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.
