It could be any soluble salt, not just sodium chloride.
Packed tower scrubbers remove soluble and noxious gases and mists in the chemical, paper and metal finishing industries.
Acid helps increase the solubility of a weakly soluble salt.
The team based at Aberdeen University has developed a method of making the drug soluble for the first time.
The enzymes break down large molecules into smaller ones so the food becomes soluble.
None of the carbonates is anything more than very sparingly soluble.
Sulfur hexafluoride is an inert, innocuous gas, poorly soluble in aqueous solutions.
The inner layer is readily soluble in any agents which are capable of breaking disulfide linkages.
Slightly soluble salts do the most damage as they expand below the surface and can push the surface off.
Nearly all copper salts are highly soluble in water.
Hydrogen fluoride is very soluble due to hydrogen bonding with water molecules.
This is poorly soluble in water but much more soluble in alcohol.
They are quite soluble in the usual organic solvents of low polarity.
It has a much narrower substrate specificity than the soluble form.
The sporocyst stage obtains nutrients by passage of soluble material across the sporocyst stage obtains nutrients by passage of soluble material across the sporocyst tegument.
Addition of it to water separated the soluble sodium carbonate from the calcium sulfide.
These crystals are comparatively soluble but nevertheless block the tubule.
Use water soluble forms of magnesium where rapid plant uptake is required.
Phloem The plant tissue that transports soluble food and minerals around a plant body (if the plant has vascular tissue ).
Low sugar ribena or soluble vitamin C tablets are suitable for this purpose.
Of course the fountain pen ink that I use in them is soluble so if you add a watercolor wash it runs.
They give a characteristic pale red precipitate with sodium pyrophosphate, soluble in an excess of the precipitant; they also form precipitates on the addition of platinic chloride and potassium ferrocyanide.
The diammine salts are prepared by the action of alkaline nitrites on cobaltous salts in the presence of much ammonium chloride or nitrate; they are yellow or brown crystalline solids, not very soluble in cold water.
According to Buchner the fermentative activity of yeast-cell juice is not due to the presence of living yeast cells, or to the action of living yeast protoplasm, but it is caused by a soluble enzyme.
These investigators considered that differences of this nature cannot be explained by the theory that it is a soluble enzyme, which brings about the alcoholic fermentation of sugar.
Mercuric fulminate is less explosive than the silver salt, and forms white needles (with 2H 2 O) which are tolerably soluble in water.
Jowitschitsch (Ann., 1906, 347, p. 2 33) inclines to Scholl's formula; he found that the synthetic silver salt of glyoxime peroxide resembled silver fulminate in yielding hydroxylamine with hydrochloric acid, but differed in being less explosive, and in being soluble in nitric acid.
He conceived of man as a product of nature that had gradually developed itself from a low condition, though he relinquished the problem of the exact mode of his first genesis and advance as not soluble by data of experience.
Amber is not homogeneous in composition, but consists of several resinous bodies more or less soluble in alcohol, ether and chloroform, associated with an insoluble bituminous substance.
The antidote in cases of carbolic acid poisoning is any soluble sulphate.
As to the formation of precipitated sulphur, Smith considers that the element first separates in the liquid S,,, condition, which is transformed into SA and finally into Sa; the insoluble (in carbon bisulphide) forms arise when little of the Sw has been transformed; whilst the soluble consist mainly of Sa.
Rotondi in 1885, however, regarded a neutral soap as hydrolysing to a basic salt, soluble in both hot and cold water, and an acid salt, insoluble in cold and sparingly soluble in hot.
To remove it, Oxland fuses the ore with a certain proportion of carbonate of soda, which suffices to convert the tungsten into soluble alkaline tungstate, without producing noteworthy quantities of soluble stannate from the oxide of tin; the tungstate is easily removed by treatment with water.
The steps in the breaking down of the highly complex nitrogenous proteid compounds contained in the humus of the soil, or applied to the latter by the farmer in the form of dung and organic refuse generally, are many and varied; most frequently the insoluble proteids are changed by various kinds of putrefactive bacteria into soluble proteids (peptones, &c.), these into simpler amido-bodies, and these again sooner or later into compounds of ammonia.
A concentrated solution of zinc chloride converts starch, cellulose and a great many other organic bodies into soluble compounds; hence the application of the fused salt as a caustic in surgery and the impossibility of filtering a strong ZnC1 2 solution through paper (see Cellulose).
From these and other considerations it is obvious that (I) the electrolyte must be such as will freely dissolve the metal to be refined; (2) the electrolyte must be able to dissolve the major portion of the anode, otherwise the mass of insoluble matter on the outer layer will prevent access of electrolyte to the core, which will thus escape refining; (3) the electrolyte should, if possible, be incapable of dissolving metals more electro-negative than that to be refined; (4) the proportion of soluble electro-positive impurities must not be excessive, or these substances will accumulate too rapidly in the solution and necessitate its frequent purification; (5) the current density must be so adjusted to the strength of the solution and to other conditions that no relatively electro-positive metal is deposited, and that the cathode deposit is physically suitable for subsequent treatment; (6) the current density should be as high as is consistent with the production of a pure and sound deposit, without undue expense of voltage, so that the operation may be rapid and the "turnover" large; (7) the electrolyte should be as good a conductor of electricity as possible, and should not, ordinarily, be altered chemically by exposure to air; and (8) the use of porous partitions should be avoided, as they increase the resistance and usually require frequent renewal.
The electrolyte is gold chloride (2.5-3 parts of pure gold per loo of solution) mixed with from 2 to 6% of the strongest hydrochloric acid to render the gold anodes readily soluble, which they are not in the neutral chloride solution.
