Initial studies to determine the thermodynamic solubility product (Ksp) of gypsum and CaCO3 were conducted. The influence of different electrolyte salts at different concentrations upon the solubility of gypsum and CaCO3 was then tested. Analytical data was utilized in conjunction with a computer to calculate the activity of CaCO3 and gypsum, the ion pair concentration and the solubility product. Indifferent salts increased the solubility of gypsum and CaCO3, and salts with a common ion decreased the solubility of gypsum and CaCO3.
Lithium was found to be the dominant monovalent cation present …

The purpose of this study was to determine the accuracy of mapping of pachic and cumulic soils in Cache County. The soil maps that were used for this study as the basemap were the Atlas sheets of the published soil survey of Cache County.
Five map units from Mendou, Nebeker, Avon, Hendricks and Winn which include almost 52 percent of the pachic and cumulic soils in the survey area were selected for this study. These five soils cover large areas when compared to other soil series and they are distributed throughout the county. All these map units were recognized as …
