  • ATOMIC STRUCTURE AND CHEMICAL BONDING

    The bioavailability of the iron in the complexes is claimed to be better than ferrous sulfate. However, when ferrous-soy hydrolysate complexes are used in beverages, discoloration and oxidation does occur. For example, chocolate beverages fortified with ferrous-soy hydrolysate complexes turn a gray color.

    The calorific value is defined as : the amount of heat produced in calories (or joules) when one gram of a substance is completely burnt. It is expressed in cal g–1 or kcal g–1 or kJ g–1. Let us compare the calorific values of methane and ethane. Their heats of combustion are – 890.3 kJ and – 1559.7 kJ.

  • Thermodynamic Modeling of Calcium Sulfate

    2020-5-14 · To prevent scaling and to recycle aqueous solutions in industrial processes, the thermodynamic properties of the CaSO4–H2SO4–H2O system are studied by thermodynamic modeling with the Pitzer model. The published solubility data of calcium sulfate hydrates in sulfuric acid solutions were collected and reviewed critically. Then, the CaSO4–H2SO4–H2O system was modeled using the …

    2012-9-1 · Establishing the detailed mechanism for ferric sulfate formation is made even more complex in that ferric sulfate phases are extensively more numerous than ferrous sulfate phases, and some of them, such as the phases belonging to the copiapite and jarosite groups may include several types of other cations (K + , Fe 2+ , etc.).

    [69] During the experiments, acid-sulfate alteration of the basalt cinders resulted in rapid decomposition of plagioclase, augite, and olivine that were exposed to acid and formation of secondary products dominated by sulfate minerals and a Si-rich gel phase. Conversely, the glass phase showed no evidence of alteration on the time scale of the ...
