A Comparative Study of Microscale and Standard Burets Mono M. Singh, Cynthia B. McGowan, Zvi Szafran, and R. M. Pike
This paper describes a comparative study of the performance of microscale titrations using 2-mL microscale burets with those using Beral pipets and normal 50- and 10-mL burets. The usefulness of a microburet in general and analytical chemistry is demonstrated by presenting results from acid-base, oxidation-reduction, precipitation, complexometric, and pH titrations.
