Effect Of Salts On The Setting Time Of Silicic Acid Gels, Gustav F. Hallstrom

Honors Theses

It has been stated by Prasad and Hattiangadi (1) that the process of setting of mixtures of solutions of sodium silicate and acetic acid consists of three stages: (a) The formation of silicic acid by the interaction of the acid with sodium silicate (b) The formation of the colloidal solution of silicic acid (c) The coagulation of the colloidal solution by the electrolytes liberated in the first reaction The present investigation was undertaken with a view to examine the effect produced on the time of setting of the silicic acid gels by the addition of extra quantities of electrolytes to …

Influence Of Temperature And Acid On Time And Set Of Silicic Acid Gels, Kenneth Jacob Frederick

Honors Theses

The underlying purpose of this research was to gain a further insight into the mechanism of the setting of silicic acid gels. The primary purpose, however, was to study the effect upon the heat of activation of the substitution of the weak acids, heretofore used almost entirely in the work done at Union College on these gels, by certain strong acids. The acids employed in this research were hydrochloric, nitric and sulphuric. Several gels were prepared from a standard silicate solution and each of these acids. Measurements of the time of set and pH were taken for each gel. Four …

A Study And Application Of The Process Of Supergene Enrichment Of Silver Ores., Arthur C. Verling

Bachelors Theses and Reports, 1928 - 1970

In many deposits of silver ores the grade of the ore de­creases considerably a few hundred feet below the surface. It is believed that in many cases the better ores owe their richness in part to the process of sulphide enrichment. It is recognized, however, that many rich silver ores are hypogene deposits that have been affected very little, if any, by processes of enrichment.

Heats Of Solution In Liquid Ammonia, Herman Dettbarn Kluge

Honors Theses

Liquid ammonia in many of its reactions and properties stimulates water. Next to water liquid ammonia is the best known electrolytic solvent. It dissolves a large number of salts to form, in general, conducting solutions, in which the ions are more mobile. Dilution Curve. The heat of dilutes is plotted against the change in the moles of ammonia. The curves approach a constant value which is the heat of dilution. These curves were plotted to compare the heat of dilution of ammonia chloride and ammonium bromide.

Change Of Conductivity Of Silicic Acid Gels Upon Setting, Robert E. Russell

Honors Theses

During the studies made on the structure of silicic acid gels, several theories of gel formation have been proposed. The theory at present under consideration has to do with the polymerization of the molecule H2SiO3 into some of structure, most probably due to the splitting out of water molecules as is indicated.

Chemical Analyses Of Some Oil-Well Waters Of Russell, Ellis And Trego Counties, H. Everett Runyon

Master's Theses

Considerable work dealing with analysis of oil-well waters of other areas has been published, but to the knowledge of the author, none has been published dealing specifically with the waters of this area. While the waters dealt with in this paper are not far different from the waters of the Midcontinent area as a whole, there are certain differences which are noticeable. For instance strontium is found in the top waters of the Eldorado, Kansas field. None has been found in this area. The sulphate content of the top water here is very high. Both apparently cause trouble at times. …

A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook

Bachelors Theses and Reports, 1928 - 1970

The accepted chemical reactions in the dissolution of gold by cyanide solutions require the presence of gold, cyanide, water, and oxygen. The importance of dissolved oxygen in cyanide solutions as a factor is recognized by those familiar with cyanidation. Manufacturers of cyanidation equipment realize the necessity of oxygen, as shown by the appliances they have developed which are attached to the agitators in order to saturate the cyanide solutions with air.

The Control Of The Grain Size Of Zinc, Oswald J. Wick

Bachelors Theses and Reports, 1928 - 1970

The use of zinc as a structural metal has been militated against by two of its properties, namely, its low tensile strength and its susceptibility to grain growth. The importance of these factors can be appreciated when it is realized that the tensile strength of coarsely crystalline cast zinc is 4,000 pounds per square inch, while finely crystalline cast zinc has a tensile strength of 12,000 pounds per square inch.

The Vitamin D And Provitamin D Content Of Some Varieties Of Utah Wheat, Harold M. Nielsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cereal grains were known to be notably deficient in the anti-rachitic principle even before the discovery of vitamin D. Clinicians had associated a type of rickets of infancy, characterized by an over-weight, flabby, bowlegged condition, with a diet consisting mainly of cereals. Mellanby (1) in 1921 concluded that this type of rickets is induced by overfeeding with carbohydrates. He also showed in the same report, however, that oatmeal, although it contains less carbohydrates than the other grains tested, possesses a special tendency toward rachitogenesis.

Amherst Township, A Regional Study, Ruth C. Rockwood

Honors Papers

Amherst township was selected as the area to be studied because it was believed to be as nearly representative of the aspects of land and life in north central Ohio as any small area that could be found. It is located on a section of the Lake Plain which has somewhat parallel lines formed by three beach-ridges, and on the northern edge of the Glaciated Plain. Then, the quarrying of the world famous Berea sandstone gives somewhat of an individual aspect to the small towns within Amherst township.

The purpose of the paper is to describe the physical landscape, and …

A Metallographic Study Of Primitive Copper Work., John A. Alley

Bachelors Theses and Reports, 1928 - 1970

The field of archaeology and that of metallurgy appear to be widely separated and in no way related. Work done in recent years, however, tends to show that, in many ways, the metallurgist can supplement and enhance the information gain­ed by the archaeologist, at least in regard to those objects which have been made of metal.
