Book Description
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1912 edition. Excerpt: ...that if kept in a dry atmosphere part of the water of crystallisation may be lost. A warm, acidified solution is oxidised by potassium permanganate in accordance with the equation H2C204-f-0=2C02+H20. Combining this with the equation for the reduction of potassium permanganate 5H2C04+2KMn04+3H2S04=K2S04+2MnS04+ 10CO2+8H2O..-.5H2C204.2H2O=2KMn04=5O=10H. 5x126 grammes =10 grammes. 63 =1 gramme=1,000 c.c. N. solution.-63 gramme =100 c.c. 10 solution. Weigh out 0-63 gramme of pure crystallised oxalic acid and dissolve in sufficient water to produce 100 c.c. Take 20 c.c, add dilute sulphuric acid and a considerable amount of water. Heat the solution to about 60 C, and titrate with the potassium permanganate solution until the appearance of a pink colour, which is permanent after warming and shaking, indicates the end of the reaction. The solution must not be heated too strongly, or a little extra permanganate may be reduced. N The factor of the potassium permanganate solution is then calculated in the usual way. The appearance of a brown colouration or precipitate during the titration indicates a deficiency of sulphuric acid, and more must be added. Potassium permanganate does not give accurate results when titrating a solution containing much free hydrochloric acid, because the hydrochloric acid reduces potassium permanganate with liberation of chlorine, according to the equation 16HCl+2KMn04=2KCl+2MnCl2+5Cl2+8H20. For the determination of iron in presence of hydrochloric acid, potassium dichromate is used. Purity of Iron Wire. The purity of a sample of iron may be determined by dissolving a known weight in dilute sulphuric acid and titrating the solution of ferrous sulphate thus obtained with standard potassium permanganate solution....
