Contact Technical Service. Ph Eur.Normal solutions and solutions bearing a specific relationship to normal solutions, and used in volumetric determinations, are designated as follows:. Solutions containing one-tenth of a gram-molecule of the compound in 1 L are designated tenth-molar, 0. A solution of approximately the desired normality or molarity is prepared and standardized by titration against a standard.
The correction factor so obtained is used in all calculations where such solutions are used. If necessary, the concentration of the solution may be adjusted to a given normality or molarity, by dilution or by addition of the appropriate reagent. The correction factor is determined by an appropriate number of replicates. The repeatability does not exceed 0. The correction factor should be redetermined frequently.
Stronger or weaker solutions are prepared and standardized in the same general manner as described, using proportionate amounts of the reagent. Volumetric solutions prepared by dilution should be restandardized as directed for the stronger solution, using proportionate amounts of reagents. Dilute solutions that are not stable, as, for instance, potassium permanganate 0. The values obtained in the standardization of volumetric solutions are valid for all Pharmacopeial uses of these solutions, regardless of the instrumental or chemical indicators used in the individual monographs.
Where the apparent normality or molarity of a titrant depends upon the special conditions of its use, the individual monograph sets forth the directions for standardizing the reagent in the specified context. For those salts that usually are available as certified primary standards or that are available as highly purified salts of primary standard quality, it is permissible to prepare solutions by accurately weighing a suitable quantity of the salt and dissolving it to produce a specific volume of solution of known concentration.
Acetic, hydrochloric, and sulfuric acids may be standardized against a sodium hydroxide solution that recently has been standardized against a certified primary standard. If a titration is carried out with the volumetric solution at a markedly different temperature, standardize the volumetric solution used as the titrant at that different temperature, or make a suitable temperature correction. Acetic Acid, Double-Normal 2 N.

Gene Expression NEW!Sodium thiosulphate solution is standardized against potassium dichromate in presence of hydrochloric acid and potassium iodide.
Potassium dichromate oxidizes the iodide ion in acidic medium to equivalent amount of iodine. The iodine formed in the reaction oxidizes sodium thiosulphate giving sodium tetrathionate ion and the end point is detected by starch solution.B.b.b.f.f. lyrics
Hence, based on the above theory our aim is to prepare and standardize sodium thiosulphate using potassium dichromate and potassium iodide in presence of hydrochloric acid and starch solution as indicator. Erlenmeyer flask.
