METRIC Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59787 22.2 Assay. The assay shall not be less than 97.0 percent as Potassium Permanganate (
6、KMnO4) when tested as follows: A 1.580 gram sample of the potassium permanganate analyte, weighed accurately to the nearest milligram, shall be dissolved in distilled water and diluted to exactly 500 milliliters in a volumetric flask. About 0.30 grams of accurately weighed reagent grade sodium oxala
7、te (dried at 105 C) shall be dissolved in 250 milliliters of dilute sulfuric acid (one volume acid plus 19 volumes distilled water) which has been previously boiled and cooled. From a burette, 39 to 40 milliliters of sample solution shall be added to the oxalate solution at the rate of 25 to 35 mill
8、iliters per minute while stirring slowly. The solution shall be allowed to stand until the pink color has disappeared and the solution shall then be heated to 55 to 60 C, and the titration shall be completed by adding the sample solution until a faint pink color persists for 30 seconds. The amount o
9、f sample solution consumed shall be corrected by titrating a blank consisting of 250 milliliters of dilute sulfuric acid (one volume acid plus 19 volumes of distilled water) as used above. The assay shall be calculated with the following formula: KMnO4(percent by weight) = BA)(100)(2.149(where: A =
10、weight of sodium oxalate, grams, B = milliliters of sample solution (corrected). 3. REGULATORY REQUIREMENTS. 3.1 Labeling, packing, and marking.
