Solutions watery

Glyceryl acetate, which is an artificial ester commonly used in the adulteration of bergamot oil, is detected fairly easily on account of its high solubility in dilute alcohol. The test is carried out as follows Ten c.c. of bergamot oil and 20 c.c. of 5 per cent, alcohol are well shaken in separating funnel, and after the solutions have separated and become clear the watery solution is run off and filtered. Ten c.c. of the filtrate are exactly neutralised with deci-normal alkali, and then 5 c.c. of seminormal alkali run in, and the whole saponified under a reflux condenser for one hour. In the case of pure bergamot oil 0 1 or at most 0 2 c.c. of semi-normal alkali will have been used up by the saponification, whilst each 1 per cent, of glyceryl triacetate present in the oil will be represented by practically 0 5 c.c. of semi-normal alkali. 

Since Steiner s aim was to improve immaterial qualities of foods, anthroposophic scientists have developed analytical methods, which aim to visualize this kind of inner quality. This is done by preparing watery solutions of the plant, meat or milk (= juices) which are then brought into reaction with metallic salts like copper chloride (copper chloride crystallization method)... 

Notice, that with these extremely good resolutions in case of surface sensing contamination of the sensitive layer with solid particles has to be avoided completely, e.g. by an appropriate filtering of the sample solutions. Notice also that the temperature coefficient of the refractive index of water is about 10-4 per °C. So if applying the surface sensing mode using watery solutions indeed a perfect balance of both branches and low temperature gradients have to be aimed at. 

Enterotoxigenic E. coli (ETEC) is the main cause of TD in Latin America, whereas in Asia it is reported in only 15% of cases. Enteroinvasive E. coli (EIEC) strains are recorded with even less frequency. ETEC is isolated in 0 to 5% of cases. Symptoms of poisoning develop after 16 hours from consumption of contaminated water, salads, cheeses, or meats. The outgrowth of ETEC rods takes place in a patient s gastrointestinal tract, where they produce thermostable and thermolabile toxins that imitate Vibrio cholerae infections. Stimulation of intestinal guanylcyclase and interruption of ion transport leads to watery stools, which do not require medical treatment or only need simple replacement of fluids and salts by means of multielectrolyte solutions. If a co-infection with EIEC strains occurs, the symptoms of enteritis will develop, with the presence of leukocytes, erythrocytes, and mucous in stools due to a cytotoxic influence of bacteria (Butterton and Claderwood, 2001). 

The watery solution of hydrogen bromide, on fractional distillation, readily yields 48 per cent hydrobromic acid, boiling at i25-i26°/76o mm. (cf. Vol. I, p. 2). 

To the crude mixture of ammonium bromide and /3-bromo-propionic acid, prepared as described on p. 25, from 317 g. of ethylene cyanohydrin, are added 1200 cc. of carbon tetrachloride and 200 cc. of the same solvent which has been shaken with the aqueous distillates the ammonium bromide is filtered off and washed with 200 cc. of carbon tetrachloride. The watery layer, amounting to about 350 cc., is separated and shaken with 100 cc. of carbon tetrachloride. To the united carbon tetrachloride solutions are added 450 cc. of 95 per cent ethyl alcohol and 10 g. of sulfosalicylic acid or phenolsulfonic acid to act as a catalyst (Note 1). 

Methylal and sodium formate may be obtained from the first distillate of the main reaction mixture. The crude distillate is placed in a flask fitted with a reflux condenser and to it is added a solution of 200 g. of sodium hydroxide in 300 cc. of water. The methyl formate is hydrolyzed to sodium formate. The methylal layer is separated, dried over calcium chloride and distilled. In this way 240-260 g. of methylal, boiling at 37-420, is obtained. By evaporating the watery portion to dryness there is obtained a residue of about 280 g. of crude sodium formate. 

If desired, the steam distillation may be omitted, since the proportion of non-volatile resinous impurities is very low. In this case the reaction mixture is allowed to cool, and the watery solution is decanted the residue is then dissolved in 1- 2 1. of benzene, and the benzene solution washed with water and with dilute alkali, after which the solvent is removed by distillation on the steam bath and the residue distilled under reduced pressure. The yield and purity of the final product are equally satisfactory. 

The remarkable fact of the presence, in the watery solution, of phosphate of ]imo, usually considered an insoluble compound, is explained by the observation of Wohler, that bone-dust, moistened will, a little water, in the course of a fow days yields to water a considerable quantity of phosphate of lime, and tins solubility rapidly increases with the putrefaction of the gelatine of bones. Hence, wherever earthy phosphates exist with organic matter, water will invariably dissolve a portion, progressively with the decomposition of the organic matter by fermentation. This fact is of the utmost importance to agriculture. 

Carbonate op Strontia is found native as stron-tianite, both massive, and in forms belonging to the square prismatic system. It is most readily prepared pure by precipitating the nitrate or chloride with carbonate of ammonia, The artificial carbonate is beautifully white and soluble in one thousand five hundred and thirty-six parts of boiling Water. It is more soluble in aqueous solution of carbonio acid, and separates in needles when, evaporated. Heated to bright redness in a stream of watery vapor it loses its carbonic acid, and becomes changed into strontia. The symbol is SrO, CO Eq. 74-00 specific gravity, 3 605. 

SOLUTION—STIR WATER INTO THE MIXTURE OF SALT AND DIRT. THE WATER WILL DISSOLVE THE SALT BUT NOT THE DIRT. YOU NOW HAVE THE SALT IN "WATERY SOLUTION."... 

Di-m-tolyl tellurium dichloride, (CH3.C6H4)2TeCl2,3 is formed when di-m-tolyl telluride in ether solution is chlorinated. The product appears as needles, sintering at 128° C. and melting at 131° to 132° C., readily soluble at the ordinary temperature in benzene, toluene, xylene, carbon disulphide, chloroform or carbon tetrachloride, less soluble in methyl or ethyl alcohol, insoluble in petroleum. When the dichloride is boiled with water a white powder separates on cooling this melts at 87° C. to a viscous oil which gradually becomes watery. Analysis shows this product to be a basic salt and not the anhydride.
