Guided word principles

We can use Le Chatelier s principle as a guide. This principle tells us that, if we add a second salt or an acid that supplies one of the same ions—a common ion —to a saturated solution of a salt, then the equilibrium will tend to adjust by decreasing the concentration of the added ions (Fig. 11.15). That is, the solubility of the original salt is decreased, and it precipitates. We can conclude that the addition of excess OH- ions to the water supply should precipitate more of the heavy metal ions as their hydroxides. In other words, the addition of OH ions reduces the solubility of the heavy metal hydroxide. The decrease in solubility caused by the addition of a common ion is called the common-ion effect.

Similarity and complementarity are two fundamental aspects of all comparisons. When making comparisons, it is usual to search either for similarity or for complementarity. It is not a mere play on words that in most comparisons the merits of similarity and complementarity are similar similarity and complementarity complement each other. The Latin saying "Similis simili gaudet", or "like likes like", as well as the saying "opposites attract" clearly apply in chemistry. For example, similarity is one of the guiding principles in solution chemistry ("like dissolves like"), whereas complementarity of shapes is important in many biochemical processes. 

While risk assessment in the context of protecting public health has been performed for many years, it is the 1983 U.S. National Academy of Sciences Report (Committee on the Institutional Means for Assessment of Risks to Public Health Commission on Life Sciences National Research Council 1983) that has served as the tenet for practicing risk assessors (see Chapter 1). Risk assessment was defined as the characterization of the potential adverse health effects of human exposures to environmental hazards. The predictive aspect of risk assessment was set by the use of the word potential. A fundamental expectation of the risk assessment process was that it should attempt to accm-ately predict adverse effects before there is evidence of disease in the population. Thus, risk assessment goes beyond the mere description of epidemiological and clinical case-control studies. In that report, the committee defined logical components of a risk assessment which still serve as guiding principles today. They were and are (a) hazard assessment or the qualitative determination that a stressor poses a hazard as evidence by causal evidence of an ill effect,... 

The Hebrew word kosher means fit or proper, and this is the guiding principle in the handling of meats for the Jewish trade. Also, only those classes of animals considered clean— those that both chew the cud and have cloven hooves—are used. Thus, cattle, sheep, and goats—but not hogs—are koshered (Deuteronomy 14 4-5 and Leviticus 11 1 -8).
