Business Requirements. Business requirements for a project are a series of needs that must be fulfilled to achieve a high-level objective. Clear business requirements help ensure that the end result of a project fulfills the stakeholders' needs. Functional Requirements.
Introduction. The solubility of aromatic hydrocarbons, such as toluene, in water, and the decrease in solubility in aqueous salt solutions is an important factor controlling the behavior of hydrocarbons in a variety of environments.. Variation of toluene solubility (expressed as C 0 / C salt, where C 0 =toluene solubility in distilled water, and C salt =toluene solubility in salt solution) versus salt concentration for various inorganic salts.
Water Small, polar organic compounds such as alcohols, aldehydes, ketones, amines, carboxylic acids, and a few phenols are soluble in water. Water-soluble compounds are tested with pH paper to see if they are acidic or basic. A pH of 4 or lower indicates a carboxylic acid. A pH of 8 or higher indicates an amine.
