After 2 hours or less, solid potassium permanganate should start to crystallize out. This effect will be manifest by an apparent sharp drop in the current efficiency as found by titration, After 2 hours, shut off the current temporarily, remove the anode and clean it (it will be found to be coated with manganese dioxide), and restore the alkalinity of the solution by adding 1 mole of solid potassium hydroxide for each faraday of electricity passed. If this is not done, potassium bicarbonate will crystallize along with the permanganate.

The pH must be kept at 7.0—7.2 for this method to be quantitative and to give a stable end poiut. This condition is easily met by addition of soHd sodium bicarbonate to neutralize the HI formed. With starch as iudicator and an appropriate standardized iodine solution, this method is appHcable to both concentrated and dilute (to ca 50 ppm) hydraziue solutious. The iodiue solutiou is best standardized usiug mouohydraziuium sulfate or sodium thiosulfate. Using an iodide-selective electrode, low levels down to the ppb range are detectable (see Electro analytical techniques) (141,142). Potassium iodate (143,144), bromate (145), and permanganate (146) have also been employed as oxidants.

Potassium iodide can also be obtained from the aq. extract of kelp or from the mother liquid remaining after the separation of sodium chloride and potassium sulphate from sea-water by evaporation. In E. Allary and J. Pellieux process,8 the liquid is evaporated to dryness and roasted in a special furnace so as to avoid a loss of iodine. The product is fractionally extracted with cold water, when a soln. is obtained which on evaporation gives a residue with 50 per cent, of alkali iodide. This product is extracted.in a special digester with 50 per cent, alcohol. The solvent dissolves little more than the iodides. The alcohol is distilled off, and on evaporation a residue containing about 34 per cent, of potassium iodide, and 66 per cent, of sodium iodide is obtained. To convert the latter into potassium iodide, the proper quantity of a soln. of potassium carbonate is added and carbon dioxide passed into the liquid whereby sodium bicarbonate is precipitated. The precipitate is separated by a filter press, and the small amount of sodium bicarbonate remaining in the soln. is separated by the addition of a little hydrochloric acid and the sodium chloride and potassium iodide separated by fractional crystallization. In E. Sonstadt s process, the mother liquid is treated with chlorine mixed with potassium chlorate or permanganate so as to convert the iodine into iodate. A soln. of a barium salt is added, and the barium iodate treated with potassium sulphate. Barium sulphate is precipitated, and the soln. of potassium iodate is evaporated to dryness and calcined to convert the iodate to iodide. The latter is purified by crystallization. 

Potassium permanganate oxidises arsenious acid rapidly and quantitatively in the presence of a trace of potassium iodide, which acts catalytically.7 The reaction takes place in the presence of mineral acid and the use of an indicator or of sodium bicarbonate is unnecessary. The titration may be carried out at any temperature up to 95° C. A slight correction is necessary for the oxidation of the iodide other iodides are less effective than the potassium salt. This method is comparable in accuracy with the iodometric method. 

The mixture of methotrexate sodium with cytarabine, fluorouracil, hydrocortisone sodium, and prednisolone sodium phosphate produces precipitate upon storage, although it is not observed immediately. A concentration-dependent photodegradation was reported for methotrexate and considered high in the presence of bicarbonate ions and unprotected polybutadiene tubings.226 Methotrexate wastes may be disposed of by oxidation with potassium permanganate and sulfuric acid or by oxidation with aqueous alkaline hypochlorite.

Xanthurenic acid is determined in bicarbonate solution by the green color resulting from addition of small amounts of ferrous salt. Its determination is not influenced by kynurenic acid, whereas the presence of xanthurenic acid can interfere with that of kynurenic acid. To avoid such interference a brief and cautious oxidation with potassium permanganate is necessary to destroy exclusively xanthvu enic acid. Afterwards the unchanged kynurenic acid is extracted at pH 2 with isoamyl alcohol, chlorinated, and reacted with quinoline. 

In llraidy s modification, which is stated to give more consistent results, 2 5 g. of very finely divided air-dry cotton is treated with a mixture of 5 c.c. of 10 per cent, copper sulphate (cryst.) and 95 c.c. of an almost saturatcd solution of sodium carbonate and bicarbonate g crystals and 50 g. bicarbonate made up to 1 litre). The cotton is immersed by means of a rod and the air bubbles are allowed to escape the flask is then surrounded with boiling water for exactly three hours. The contents arc filtered off on an asbestos filter and washed first with dilute sodium carbonate solution and then with water. Then the residual cuprous oxide is dissolved by treatment with a solution containing 100 g. of iron alum and 140 g. of concentrated sulphuric acid per litre. Two such treatments usually suffice. The fitter is tben washed with 2 Af-sulphuric acid the combined filtrate and washings arc titrated with A /25 potassium permanganate solution. According to Brissaud the test is affected by air. 

Preparation. Singhla reports an improved procedure for the preparation based on a patent by H.-J. Teuber. Hydroxylamine disulfonate, HON(SOaNa)2, is prepared from sodium nitrite, sodium bicarbonate, and sulfur dioxide and then oxidized with potassium permanganate with pH-control. Manganese dioxide is removed by centrifugation followed by filtration. Fremy s salt separates from the filtrate after addition of KC1 and is recrystallized from 1 N KOH. Material prepared in this way can be stored in the cold for several months.

The sugar (up to 100 mg) in concentrated HCI (250 gl) is stirred or shaken with benzaldehyde (250 /il) at room temperature for 15 h. The mixture is diluted with chloroform (500 fi ) and the solution is washed to neutrality with successive equal volumes of 0.6 M sodium bicarbonate. The chloroform solution is dried and evaporated to dryness. The residue may be dissolved in a suitable solvent for TLC, with detection by spraying with 0.1 M potassium permanganate in 1 M H2SO4 and heating [4j. 

Potassium hydroxide, like its sodium counterpart, is a versatile intermediate in the production of chemicals. Because KOH is more expensive, NaOH dominates in large-scale uses, and potassium chemicals are largely restricted to specialty markets. They are often more soluble and more reactive than the corresponding sodium chemicals, and this fact is responsible for many of their applications. Widely used derivatives include acetate, bicarbonate, bromide, cyanide, ferrocyanide, oxalate, permanganate, and phosphate. The derivative with the greatest market probably is potassium carbonate, which is discussed in Section 7.5.2.2A. 

Wear latex gloves to keep the acids from contacting your skin when you prepare and handle solutions of potassium permanganate or chromic acid.These solutions cause unsightiy stains on your skin for several days, and the chromic acid-sulfuric acid soiution may cause severe chemical burns. If these oxidants contact your skin, immediateiy fiood the affected area with water. In the case of chromic acid, also rinse the area with 5% sodium bicarbonate solution.
