Sodium photographic fixative

Photography. Sodium sulfite is useful as a reducing agent in certain photographic fixing baths, developers, hardeners, and intensifiers (334). However, the principal use is as a film preservative and discoloration preventative (see Photography). [Pg.149]

Use Manufacture of sodium ferricyanide, blue pigments, blueprint paper, anticaking agent for salt, ore flotation, pickling metals, polymerization catalyst, photographic fixing agent. [Pg.1144]

Used in photographic fixing baths. Also referred to inconecttyeiS sodium hyposulfite. Apparent melting point due to loss of water of crystallization. Other apparent melting points 100 C (on loss of all water of crystallization). ... [Pg.822]

Because of its extreme insolubiUty, barium sulfate is not toxic the usual antidote for poisonous barium compounds is to convert them to barium sulfate by administering sodium or magnesium sulfate. In medicine, barium sulfate is widely used as an x-ray contrast medium (see Imaging TECHNOLOGY X-RAY technology). It is also used in photographic papers, filler for plastics, and in concrete as a radiation shield. Commercially, barium sulfate is sold both as natural barite ore and as a precipitated product. Blanc fixe is also used in making white sidewall mbber tires or in other mbber appHcations. [Pg.482]

Consequently, the use of potassium perdisulphate has been suggested to effect the removal of sodium thiosulphate from photographic negatives after fixing. 8... [Pg.185]

The formation of these relatively stable complex salts explains the solubility of the silver halides in sodium thiosulphate solution and the value of such a solution for fixing photographic prints. In many cases the complex salts have been isolated in the solid state,10 for example,... [Pg.199]

How can one verify, just by looking at the Latimer diagram of silver, that sodium thiosulfate (hypo) is useful in photographic processes that require the removal of excess, wrested silver halide Is this process (fixing) actually a redox reaction Explain... [Pg.322]

If the solubility of silver bromide or any slightly soluble silver salt could not be increased, we would not be able to fix a photographic image. When sodium thiosulfate reacts with insoluble silver bromide, the silver complex produced, Ag(S203) 23 , is quite... [Pg.308]

With silver halides sodium thiosulphate forms a soluble sodium silver thiosulphate, and is employed as a fixing material for photographic plates and paper to remove the portion of silver salt unaffected by light ... [Pg.124]

Applications Ca. 90% of the sodium thiosulfate produced is utilized as a fixing salt in the photographic industry. It is also used as an antichlorination agent in bleaching plants and in paper manufacture. Ca. 30 10 t were produced in the USA in 1995. [Pg.122]
