Artificial salts

Third, Boulduc s careful analysis yielded the important discovery that Glauber s salt, long known only in the laboratory, existed in nature. The next year, he identified two other natural salts as Glauber s salt because they were composed of vitriolic acid and the base of marine salt. These discoveries weakened Glauber s original opinion that his salt was not found all formed in nature and helped close the gap between the natural and the artificial salts. In the ensuing years, Boulduc continued to apply his techniques to a variety of subjects in order to refute the assumption that salts were the artificial products of fire. He hoped to discover a mineral alkali, or a natural and fossil alkali that existed before the fire analysis. Boulduc s careful work won esteem among the academicians. When Boulduc took up the analysis of another mineral water, Fontenelle praised the precise and exact nature of his work ...

Winkler and Junge (1972) prepared an artificial salt mixture having a composition similar to that often found in continental aerosols. Its growth behavior resembled that of natural aerosols, provided allowance was made for the influence of insoluble material. 

We also examined the effect of petuniolide C upon the brine shrimp, Artemia salina, in order to test the response of another class of arthropod toward this chemical. This crustacean has been suggested as a general experimental subject in toxicity determination of chemical substances toward invertebrates, and for the indication of cytotoxicity (21, 22). Solutions for the test were prepared by adding stock solutions of XVIII in ethanol to containers of artificial salt water (1% EtOH final concentration) with sonic agitation. Even with added ethanol, the solubility limit of the steroid was about 1.0 ppm. Newly hatched brine shrimp were added to these solutions, and controls were run using salt water and salt water containing 1% ethanol. After 24 hr., no mortality was observed for the EtOH controls, and no toxic effect was seen for petuniolide C at 1.0 ppm.

The production of artificial salts by dissolving a metal or other mineral pure substance in an acid was performed in various ways significant for the initial understanding of these operations. When metals dissolve, the acid functions as both reagent and solvent. The salt produced in this process has to be separated from the solvent, often... 

Atmosphere-Accelerated Outdoor Tests with artificial salting to determine general corrosion resistance. 

Testing for flavor-impact chemicals in fermented pickles was compared using solid-phase extraction (SPE), purge-and-trap (P T) on Tenax, and SPME (5). Determination of which chemicals were the most significant flavor-impact chemicals was made by olfactometry experiments employing the detection frequency method (for details, see Chapter 12) and by recombination studies (i.e., adding suspect flavorants to an artificial salt brine solution to determine which potential flavorant and/or combination of flavorants most closely matched the flavor of the pickle brine).
