Silver nitrate is a chemical compound with chemical formula AgNO3. This nitrate of silver is a light-sensitive ingredient in photographic film and is a poisonous, corrosive compound. Silver nitrate crystals can be produced by dissolving silver in nitric acid and evaporating the solution. The compound notably stains skin a greyish or black color that is made visible after exposure to sunlight. Silver nitrate has been used as an antiseptic, dropped into newborn babies' eyes at birth. This is to prevent contraction of gonorrhoea or chlamydia from their mother. A very weak solution is used for this, (about 1%) and there are very few side effects. Mythically, silver nitrate was used as a method of killing vampires, with the silver nitrate generally being injected into a bullet cartridge or used in a hypodermic needle. Fused silver nitrate, shaped into sticks, was traditionally called lunar caustic and used as a cauterizing agent. It can also be used in wound management to 'knock back' over-granulation of tissue in healing wounds such as ulcers and sinuses. [edit]

Silver nitrate can be used in a medical environment as a chemical cauterizing agent and medicinal caustic. A typical applicator is composed of 75% silver nitrate with 25% potassium nitrate. As the silver nitrate contacts with water (in the blood) the compound goes into solution forming nitric acid. The acid subsequently is responsible for the cautery effect. As mentioned above this will typically result in a black or greyish staining of the skin. This staining is caused by the accumulation of the silver and will typically go away as the body rids itself of the mineral. Retrieved from "http://wiki.bmezine.com/index.php/Silver_Nitrate"

What is brown spot under nose after cauterization?

That's Silver Nitrate, which is the chemical used to cauterize the blood vessel. I've had two nose cauterization done recently due to nosebleeds, and both times a bit of silver nitrate gone onto my skin right outside my nostril. Initially I was worried that I might not be able to get it off, but after about 2 1/2 days, I see that it was flecking off a bit when I rubbed it, and so I lightly scratched it, and the brown spots came off! ^-^

Copper will react with silver nitrate to form copper nitrate and silver?

In certain reaction conditions, yes. Copper is more reactive than silver, so it should react with the nitrate molecule to form copper nitrate while precipitating the silver. *Are you thinking about separating silver from photographic fixer?

What mass of silver chloride can be produced from 1.20L of a 0.151M solution of silver nitrate?

By definition, a 0.151 molar solution contains 0.151 moles of silver nitrate per liter of solution. Therefore, 1.20 L will contain 1.20(0.151) or 0.181 moles of silver nitrate. The formula units of both silver nitrate and silver chloride contain one atom of silver each, and the solubility product constant of silver chloride is sufficiently small that as many moles of silver chloride as of silver nitrate used can be completely converted to silver chloride, for which the gram formula unit mass is 143.22. Therefore, 143.22(0.181) or 26.0 grams of silver chloride, to the justified number of significant digits, can be formed
