Ferric acetates hydroxids

Ferric orthoarsenite cannot be prepared directly from ferric hydroxide and arsenious oxide.4 The brown product obtained by shaking freshly precipitated ferric hydroxide with an aqueous solution of arsenious oxide has been described 5 as a basic ferric arsenite of composition 4Fe203.As203.5H20. A similar substance is obtained by adding aqueous arsenious oxide or sodium arsenite to ferric acetate solution. If ferric chloride, sulphate or nitrate is used, the ferric salt is not completely precipitated. The product is oxidised in moist air, and decomposes when heated. It is very doubtful whether this is a chemical individual, however, for it has been shown that the removal of arsenious oxide from the solution by the ferric hydroxide is due to adsorption, the amount removed depending upon the conditions and the age of the adsorbent. This subject is discussed more fully on p. 154. [Pg.168]

Fe(C2H302)3 (aq.). Thomsen15 measured the heat of reaction of aqueous ferric sulfate with aqueous barium acetate to be 20.21. Ber-thelot5 measured the heat of reaction of aqueous ferric acetate with aqueous potassium hydroxide, and the reciprocal heats of mixing involving Fe, C2H302 , H% and Cl-. Data on the heat of dilution of aqueous ferric acetate were reported by Berthelot5... [Pg.313]

Ferric arsenite, 4Fe203.As203.5H20, may be prepared by shaking freshly precipitated ferric hydroxide with an aqueous solution of arsenious oxide, or by adding sodium arsenite (or an aqueous solution of arsenious oxide) to ferric acetate. It is brown in colour, and oxidised by the air when moist.2... [Pg.192]

Hydroxy-5,6,7,8-tetrahydro-2-naphthaldeJi,yde —To 2 0 g (0 011 mole) of the methoxyaldehyde in 15 ml of boiling acetic acid 4 ml of 48% hydrobromic acid was added. The mixture was refluxed 40 min, diluted to 200 ml. with water, and extracted with ether. The ether was shaken with 5% sodium hydroxide and the latter acidified to yield 0-4 g (22%) of light tan solid, m.p. 52-55°. Two recrystallizations afforded the spectral sample, m.p. 55 2-56 4° (lit. m.p. 56-57°[7]), deep blue colour with ferric chloride in alcohol. [Pg.471]

This process is evidently a supplementary mordanting with acetate of iron and copper or iron sulphate. The Sinopian earth was essentially ferric hydroxide or oxide. [Pg.97]

E. P. Alvarez 2 found that the pemitrates react with soln. of lead acetate (white precipitate), silver nitrate (white precipitate), mercurous nitrate (white precipitate with rapid decomposition), mercuric chloride (red precipitate), copper sulphate (blue precipitate), zinc and cadmium sulphates (white precipitate), bismuth nitrate (white precipitate), gold chloride (slight effervescence and escape of oxygen), manganous chloride (pink precipitate), nickelous chloride or sulphate (greenish-white precipitate), cobaltous nitrate and chloride (pink precipitate), ferrous sulphate (green or bluish-green precipitate), ferric chloride (red ferric hydroxide), and alkaline earth chlorides (white precipitates). The precipitates are all per-salts of the bases in question. [Pg.384]
