Edta Titrations With Mercury Amalgam Indicator Electrodes, Kenneth Deardorff Legg
Honors Theses
A study of the characteristics of certain mercury amalgam electrodes as used in these types of analysis has been made. The overall applicability and usefullness of a bismuth-mercury slurry electrode is studied. The effect of several solution conditions on the electrode characteristics has been observed.
A Polarographic Analysis Of The Tetracyanoaurate (Iii) And The Dicyanoaurate (I) Complexes, David Jefferson Mcclemens
A Polarographic Analysis Of The Tetracyanoaurate (Iii) And The Dicyanoaurate (I) Complexes, David Jefferson Mcclemens
Honors Theses
A polarographic analysis of the two gold complexes, dicyanoaurate (I) and tetracyanoaurate (III), was undertaken. Both complexes were shown to have distinguishable current-voltage curves. Previous work on the dicyanoaurate (I) was confirmed, and new data was added for the low concentrations. The tetracyanoaurate (III) was investigated, and the half-wave potential was found to be -0.32 volts. Maxima problems with the complex were encountered and resolved.

A Proposed Method Of Separation And Analysis Of The Au(Cn)2 And Au(Cn)4 Complexes, Richard Edward Beane
A Proposed Method Of Separation And Analysis Of The Au(Cn)2 And Au(Cn)4 Complexes, Richard Edward Beane
Honors Theses
Due to its relative scarcity, gold has always held a high value to civilizations compared to other metals which are more common and easier to obtain. Various methods of extraction of the metal have been used throughout history, the most successful of which are washing and dissolution. The most important method of recovery at the present time is dissolution by cyanidation. In order to study the electron exchange between the Au(CN)-2 and Au(CN)-4 complexes, it must be possible to obtain both separately, mix them together in solution, separate them once again, and distinguish between the two complexes to determine the …
Synthesis Of The Bicyclo-(5,5,0)-Dodecane System, Anthony Angelo Gallo
Synthesis Of The Bicyclo-(5,5,0)-Dodecane System, Anthony Angelo Gallo
Honors Theses
The bicycle-(5, 5, 0)-dodecane system consists of two fused seven membered rings. (I) The numbers five, five and zero are arrived at by the fact that counting the number of carbon atoms from one bridgehead carbon to the other yields five, five and zero by the three possible routes. This system can exist in several states of unsaturation. One such state has been given the name heptalene. (II) The object of this project is to propose a new synthesis of the bicycle-(5, 5, 0)-dodecane system.
On The Recovery Of The Nitrates Of Uranyl Ion And Silver (I) Ion From Laboratory Residua, Bruce Bertolette Hardman
On The Recovery Of The Nitrates Of Uranyl Ion And Silver (I) Ion From Laboratory Residua, Bruce Bertolette Hardman
Honors Theses
Uranium became known in the same epoch of history that saw the discovery of the planet Uranus. It was so named. Uranium is a rather active element and never occurs free in nature. Its ores include uraninite is by far the most important. This ore is sometimes called pitchblende and has a simplest empirical formula of UO2. Due to the fact that it is always found partially oxidized its composition may range between that of UO2 and U3O8. This latter form contains both tetra and hexavalent uranium. An illustrative structure is given below. It is sometimes regarded as uranyl uranate, …
An Examination Of Basicity Functions, Lewis Morton Gedansky
An Examination Of Basicity Functions, Lewis Morton Gedansky
Honors Theses
Acids and bases have long been subjects of interest to the chemist. These two classes of chemical compounds play an important role in the chemical world in regards to their reaction with each other and their use as catalytic agents. They are known to react with each other in either of two ways. The reaction which is most familiar is the standard neutralization reaction which results in the formation of a salt and water. It can be illustrated by the reaction of an acidic substrate, HA, reacting with the base, sodium hydroxide. Such a reaction conforms with the Bronsted-Lowry definition …
The Determination Of The Ratios U234/U238 And Th228/Th232 As Leached From Storm King Granite, James Robert Lawrence
The Determination Of The Ratios U234/U238 And Th228/Th232 As Leached From Storm King Granite, James Robert Lawrence
Honors Theses
In nature there are three major decay series that involve naturally occurring uranium and thorium as parent nuclides. Two of the three series; U-238, TH-232 and U-235; are shown in figure I. Of the three series two, U-238 and the Th-232 series, are examined in the study. This is because the amount of U-235 in nature is very small relative to the amount of U-238 and Th-232. This study is concerned with the presence of U-238 and Th-232 and their uranium, thorium and radium daughter products in the silicic intrusive rock, Storm King Granite. Uranium and thorium have large iconic …
An Investigation Of The Ternary System: Magnesium Sulfate - Urea - Water, David Brian Holland
An Investigation Of The Ternary System: Magnesium Sulfate - Urea - Water, David Brian Holland
Honors Theses
Magnesium sulfate hydrate and urea are common constituents of many commercial fertilizers. It is the purpose of this investigation into the ternary system: magnesium sulfate – urea – water to try to resolve these discrepancies and also to further investigate the ternary system.
A Hydrogen Electrode Via Ferrous Ion And Ultraviolet Light, Richard Leslie Harlow
A Hydrogen Electrode Via Ferrous Ion And Ultraviolet Light, Richard Leslie Harlow
Honors Theses
The purpose of this research is to investigate the photoelectric properties of an acidified ferrous-sulfate solution. It is known that in the presence of ultraviolet light, the equilibrium is shifted to the right. The idea is proposed that the hydrogen gas produced by this reaction might be absorbed on a platinum grid, thereby creating a hydrogen electrode. A cell is thus proposed in which two platinum electrodes are immersed in the same solution of ferrous sulfate and sulfuric acid. The area surrounding one electrode is to be illuminated with ultraviolet light. Some of the hydrogen gas produced in that area …
Synthesis Of 1-Diazo-3-Methoxy-3-Phenyl-2-Propanone And Reaction With Boron Trifluoride Etherate, Harvey Harris Kagan
Synthesis Of 1-Diazo-3-Methoxy-3-Phenyl-2-Propanone And Reaction With Boron Trifluoride Etherate, Harvey Harris Kagan
Honors Theses
It has been found that the normal reaction of diazoketones with an acid to form substituted methyl ketones is often subverted by cyclization to form closed chain cyclic ketones. Some work has been done with aromatic diazoketones but very little has been done with the aliphatic diazoketones. The object of this research was to bring about ring closure of a four membered ring from an aliphatic diazoketone. It was decided to put a phenyl group on the aliphatic chain in order to obtain crystalline derivatives. Specifically, the object of this work was to bring about the cyclization of 1-diazo-3-methoxy-3-phenyl-2-propane. The …
Synthesis Of Some Polymers From Benzyl Alcohol Or Its Derivatives, John Oliver Rosser
Synthesis Of Some Polymers From Benzyl Alcohol Or Its Derivatives, John Oliver Rosser
Honors Theses
The original project was concerned with the production of ortho-nitro-para-[w-(β-napthyl)]-ethyl-benzyl alcohol or its alkyl-ether. This was to be accomplished by following a five step synthesis, the first step of which was a Friedel Crafts acylation of methyl-benzyl ether according to reaction (1).
Heats Of Solution Of Saturated Mixed Electrolytes, Stephen Alan Rudolph
Heats Of Solution Of Saturated Mixed Electrolytes, Stephen Alan Rudolph
Honors Theses
Reliable data on heats of solution of concentrated mixed electrolytes is a rather scarce. This work purports to give formulas for the heat of solution at saturation of an electrolyte in a solution saturated with respect to still another electrolyte. These formulas are in terms of solubility data and non-calorimetric thermodynamic data and are as follows.
Phosphoric Acid - Catalyzed Hydrolysis Of Benzeneboronic Acid, Kenneth Sumner
Phosphoric Acid - Catalyzed Hydrolysis Of Benzeneboronic Acid, Kenneth Sumner
Honors Theses
At a phosphoric acid concentration of over 80%, the kinetics are not first - order, but instead, the reaction appears to be autocatalytic. Is it the purpose of this research to determine if this phenomenon is real, and if so, to elucidate the cause of the autocatalysis.
