Reactions Between The Stannous And Arsenate Ions In Silicic Acid Gels, Willard Merle Farr Jan 1931

Reactions Between The Stannous And Arsenate Ions In Silicic Acid Gels, Willard Merle Farr

University of the Pacific Theses and Dissertations

Observation of crystal growths resulting from the chemical interaction of stannous chloride and sodium arsenate in silicic acid gels revealed the following very interesting fact. Gels identical in every respect except acidity, contained crystal growths varying greatly in appearance.

The purpose of this investigation was, therefore, to allow stannous and arsenate ion to combine in a series of accurately prepared gels, identical in all respects except the acid content, and to observe the effect upon crystal growth of: (1) varying the acid concentration; and (2) varying the kind of acid


A Preliminary Study Of Electrical Conductivity In Silicic Acid Gels, Rudolph C. Ferguson Jan 1931

A Preliminary Study Of Electrical Conductivity In Silicic Acid Gels, Rudolph C. Ferguson

University of the Pacific Theses and Dissertations

In this project the author has attempted to determine the specific conductance of a gel of known composition; the changes, if any, of conductance in a gel as it sets; and the changes in conductance due to the diffusing of an electrolyte through the gel.
