An Investigation Into The Bromate Method Of Manganese Determination, Ray A. Bunday
An Investigation Into The Bromate Method Of Manganese Determination, Ray A. Bunday
Electronic Theses and Dissertations
Throughout the history of research in the science of Chemistry the problem of the quantitative determination of manganese has always been a perplexing one. The results have usually fallen short of the theoretical value and has necessitated the application of an empirical factor(1) which is always undesirable to the true research scientist, if not to the commercial analyst.
Selenium In Proteins From Toxic Foodstuffs, Edgar Page Painter
Selenium In Proteins From Toxic Foodstuffs, Edgar Page Painter
Electronic Theses and Dissertations
The importance of the selenium problem has been established. Knight (1) in an address before The Association of Official Agricultural Chemists summarized the progress made on the problem, conservatively emphasized its importance, and stressed the need for extensive research. It is a paramount problem not only in South Dakota, but in many other states as well.
Determination Of The Limits And Accuracy Of Potassium Ferricyanide As An Outside Indicator In The Determination Of Iron And A Comparison Of This Outside Indicator With Diphenylamine As An Inside Indicator, Eugene D. Burr
Electronic Theses and Dissertations
In the volumetric course as offered by the Department of Chemistry of South Dakota State College for the spring term of 1931, we experienced difficulties in the methods which we were using for the determination of iron. The general method used was that of Penny's, using an outside indicator of potassium ferricyanide, and titrating with potassium dichromate.
