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.
Highly soluble compounds, such as NaCl, break apart completely, while compounds with low solubilities, such as lead sulfate (PbSO 4) do so only partially. Compounds with nonpolar molecules do not dissolve. How Ionic Compounds Dissolve. In solution, each water molecule acts like a tiny magnet that creates a force of attraction on the ions in the solute.
