Solid silver nitrate - think, youPhotosensitivity[ edit ] Although photographic processes have been in development since the mids, there were no suitable theoretical explanations until with the publication of a paper by R. Gurney and N. Factors such as crystal growth, impurities, and surface defects all affect concentrations of point ionic defects and electronic traps, which affect the sensitivity to light and allow for the formation of a latent image. Most defects, such as interstitial silver ion concentration and surface kinks, are inversely proportional to crystal size, although vacancy defects are directly proportional. This phenomenon is attributed to changes in the surface chemistry equilibrium, and thus affects each defect concentration differently. Although impurities in the silver bromide lattice are necessary to encourage Frenkel defect formation, studies by Hamilton have shown that above a specific concentration of impurities, the numbers of defects of interstitial silver ions and positive kinks reduce sharply by several orders of magnitude. After this point, only silver-ion vacancy defects, which actually increase by several orders of magnitude, are prominent. The lifetime of a photohole, however, does not correlate with that of a photoelectron. This detail suggests a different trapping mechanism; Malinowski suggests that the hole traps may be related to defects as a result of impurities. Agv The formation of the h.

Silver nitrate is a compound written as AgNO3. Due to the ionic behaviour of this compound, it is soluble in water and breaks down into compounds. Silver nitrate is a precursor to plethora of silver compounds, including http://rectoria.unal.edu.co/uploads/tx_felogin/why-do-cosmetic-for-our-business-which/reasons-why-youth-join-gangs.php used in photography.
Because of its photosensitivity, AgNO3 solid silver nitrate stable when exposed to light compared to the silver halide used in photography. Lunar caustic The nitrate ion described above consists of a nitrogen atom surrounded by three oxygen atoms.
The nitrogen-oxygen bonds of these ions are the same. It can be seen that the structure of the nitrate ion is stabilized by resonance.

Physical properties The molar mass of silver nitrate isgrams per mole. AgNO3 is solid silver nitrate colorless, odorless solid. When stable, the density is 4. The melting point and boiling points of silver nitrate are Like most ionic compounds, silver nitrate is easily soluble in water.
The crystal structure of AgNO3 is a rhombus. Chemical properties The dangers of AgNO3 include toxicity and corrosion. Copper replaces the silver found in this compound to form copper nitrate.

Metal nitrates generally decompose to form metal oxides, but it can be seen that the decomposition reaction source silver nitrate leads to the formation of elemental islver because silver oxide decomposes at a much lower temperature than AgNO3. Silver nitrate material Silver nitrate is commonly used in many fields such as biology, chemical synthesis, and medicine.
Some of these uses of AgNO3 are listed below.
Silver nitrate is a very versatile compound because nitrate ions can be replaced by other ligands that can bind to silver ions.]
