Specific volume sodium chloride solutions

Method. For plasma samples, dilute 1 volume with 1 volume of the Buffered Sodium Chloride Solution. For urine samples, dilute 1 volume with 9 volumes of the reagent. Insert file elecfiode of mi ion-specific fluoride meter into the diluted sample and allow to equilibrate for 30 minutes. Record the ion potential of the solution.

The dosage as an additive in parenteral fluid therapy is predicated on specific requirements of the patient. The appropriate volume is then withdrawn for proper dilution. Having determined the mEq of sodium chloride to be added, divide by 4 to calculate the number of mL to be used. Withdraw this volume and transfer into appropriate IV solutions, such as 5% dextrose injection. The properly diluted solution may be given IV. 

The solubility of a substance describes the maximum mass of that substance that can dissolve in a given mass or volume of solvent at a specific temperature to form a stable solution. The solution is saturated with solute. The solubility of sodium chloride, NaCl, at 20°C is 35.9 g in 100 g (100 mL) of water. For potassium iodide, KI, it is 144 g/100 g of water at 20°C. Yes, this liquid solution has a mass of solute greater than the mass of solvent. Water is classed as the solvent because both it and the solution are liquid. 

Ethyl Ether, (C2H5)20, is the most important member of the class of compounds known as ethers. It is usually called ether (without the prefix ethyl). It is a very mobile, colorless liquid, which boils at 34.5° and solidifies at —117.6°. On account of its low boiling-point it is very volatile, and as its vapor forms an explosive mixture with air, great care must be exercised in its use. Ether is an excellent solvent for many organic substances, and is much used in the laboratory for crystallization and for extraction of substances from aqueous solutions. One volume of ether dissolves in about 11 volumes of water at 25°. As it is less soluble in water which is saturated with sodium chloride, the latter is frequently added to aqueous solutions which are to be extracted. Ether dissolves about two per cent of its volume of water. It has the specific gravity... 

From the results obtained by microscopic observation, the maximum specific volume of the swelling is 284.7 80.7 in water. By the addition of sodium chloride or acids, the maximum specific volume of the swelling and the final volume of the deswelling were greatly decreased. Whether the reaction is the swelling or the deswelling, the gel volumes at the equilibrium state in sodium chloride or acetic acid solution were almost the same. 

In a later report, Luecke and Pearson (55) devised a method for the estimation of free choline in tissues which appears to be more specific. The tissues were extracted with an aqueous solution of sodium acetate at pH 4.6 and the extracts were treated with acetone to precipitate lecithin. After rranoving the acetone and bringing the remainder to a definite volume, an aliquot was passed over activated Decalso. Choline was then eluted from the column with 5% sodium chloride and the eluate assayed for choline microbiolo cally (43). The free choline content of plasma was not reinvestigated by this method but 2% of the total choline in rat liver was reported to be in the free form. Kidney and brain had only negligible quantities of free choline.
