Silver Permanganate. Silver permanganate [7783-98-4] AgMnO, is a violet soHd formed when a potassium permanganate solution is added to a silver nitrate solution. It decomposes upon heating, exposure to light, or by reaction with alcohol. 

To assess suitability of plastic storage containers for distribution of silver nitrate, behaviour under fire exposure conditions of various polymers in contact with the salt was examined. All polymers tested burned vigorously. 

There is no historical information in humans to suggest that silver affects reproduction. In an early animal study, there was no reduction in fertility or observable changes in spermatozoa after 2 years of exposure to 89 mg silver/l /day as silver nitrate or silver chloride in the drinking water. 

Silver nitrate is toxic by all routes of exposure. Ingestion can cause severe gastroenteritis. Also, it is a severe irritant to eyes and skin. 

In the absence of solvent, disubstituted alkynes react with silver nitrate and silver perchlorate to form colorless complexes of variable stoichiometry which readily lose the alkyne on exposure to air (51). 

Diammino-silver nitrate forms glistening rhombic or prismatic crystals which blacken on exposure to light. It is fairly stable, and may be heated to 100° C. without loss of ammonia. Further heating causes it to decompose, and finally to melt with evolution of nitrogen and ammonia, leaving a residue of metallic silver and ammonium nitrate. It is soluble in water, but partial dissociation takes place so that the solution is alkaline in reaction, and it therefore yields a precipitate of silver chloride and soluble chlorides. Certain of the metals—for example, zinc, cadmium, and copper—quickly reduce the ammine in solution to metallic silver. 

Printing-out emulsions. These emulsions produce images on exposure without development. They are used largely for making portrait proofs which are distinguished by their red or purplish color. Emulsions of this type differ from others in that they usually contain silver nitrate, some free silver, silver salt of an organic acid and a weak free acid. These are known as P.O.P. Proof Papers. 

Silver phosphate (Ag3P04), [CAS 7784-09-01 yellow precipitate, by reaction of silver nitrate solution and disodium hydrogen phosphate solution, soluble in HNO3 and in NH4OH, turns dark on exposure to light. 

In the RS process of Itek Corporation, a coating of a photoconductor such as TiC>2 is used to form upon exposure a reversible latent image, which is converted to a latent image in Ag° nuclei by treatment of the exposed Ti02 with a silver nitrate solution. The coating can then be treated...
