Sulfuric acid balanced chemical reactions

Balanced chemical reactions are critical to the chemical industry. Plant managers must know the amount of reactants necessary to yield a product to keep production lines moving. If reactants or products are not pure, this must be taken into account. Alternative reactions can be examined to find the most cost-effective process. For example, a fertilizer may be produced using one process with sulfuric acid as a reactant or another process that starts with ammonium carbonate. Working through the balanced equations for each process would help decide which process to adopt.

Figure 4-13 shows an example from a three-dimensional model simulation of the global atmospheric sulfur balance (Feichter et al, 1996). The model had a grid resolution of about 500 km in the horizontal and on average 1 km in the vertical. The chemical scheme of the model included emissions of dimethyl sulfide (DMS) from the oceans and SO2 from industrial processes and volcanoes. Atmospheric DMS is oxidized by the hydroxyl radical to form SO2, which, in turn, is further oxidized to sulfuric acid and sulfates by reaction with either hydroxyl radical in the gas phase or with hydrogen peroxide or ozone in cloud droplets. Both SO2 and aerosol sulfate are removed from the atmosphere by dry and wet deposition processes. The reasonable agreement between the simulated and observed wet deposition of sulfate indicates that the most important processes affecting the atmospheric sulfur balance have been adequately treated in the model.

One harmful effect of acid rain is the deterioration of structures and statues made of marble or limestone, both of which are essentially calcium carbonate. The reaction of calcium carbonate with sulfuric acid yields carbon dioxide, water, and calcium sulfate. Because calcium sulfate is marginally soluble in water, part of the object is washed away by the rain. Write a balanced chemical equation for the reaction of sulfuric acid with calcium carbonate.

One essential aspect in evaluating the presence of these compounds in different matrices is that when added to foods they often disappear as a result of reversible and/ or irreversible chemical reactions. When sulfites are added to foods, they come into contact with an aqueous medium there and undergo a process of dissociation in which the oxyanions may be separated from their cations depending on the pH, ionic strength and temperature of the medium. This process produces a dynamic chemical balance among species (sulfur dioxide, sulfurous acid, and sulfite and bisulfite anions) that tends toward the formation of one or another depending on the conditions in the medium so that all the forms coexist but in different proportions in different conditions (Wedzicha, 1992 Margarete et al., 2006).
