By using chromatization method thus separation of colours of combined sources.
ANSWER
If you have black stains on your skin from playing with silver salts, you basically can't remove them. The black colour is caused by silver particles which get into pores and the surface layers of your skin. Silver is soluble in nitric acid but this is NOT an option for cleaning your hands. Luckily, skin is continually replaced and grows from layers the silver particles don't reach so, in a couple of weeks, the stains will start to fade and disappear in about two to three weeks depending on how dark the stains are.
Silver chloride is a notoriously insoluble white crystalline solid. It will decompose, like most silver salts, when exposed to light. This is the principle of the old black and white Photography.
BeCl+AgN2+H2O----->BeN2+AgCl
Silver is used in film media because it tarnishes better than other materials.Tarnish is the process of oxidation, where a metal turns from some some shiny color to a darker non-shiny color.Three Examples of Tarnish:Gold: Starts a bright shiny gold color and tarnishes to a slightly darker dull gold colorCopper: Starts a bright shiny orange-gold color and tarnishes to a green patina colorSilver: Starts a bright almost white color and tarnishes to a very dark grey, almost black colorSilver provides the best tonal range, from light to dark. It can capture light from pure white to pure black (or very close).Additionally, silver tarnishes very consistently. This provides a smooth transition from light to dark on film.
Cameras are of two typesDigital:These cameras have photo sensitive transistors which actually help to generate different voltages for different colors of light and they get converted to different values through a ADC and are processed to generate a picture.Older cameras:They contain silver compound (mostly Agcl) coated reel (photo reel which we buy) which is exposed to atmosphere for a split second when the shutter opens and thus by different intensities a different pattern is formed producing a photo. That is the reason negative cleaning is done is dark rooms.There are several type of camera but a still digital camera captures an image and stores it as a data file. A still film camera captures light images on a light sensitive film which can then be developed into photographs.
AgCl is silver chlorideThe color of silver chloride (AgCl) is white.
brown
These are silver halides as AgCl and AgBr.
AgCl is relatively insoluble.
The treatment of AgCl involves filtering and washing the precipitate with water to remove any impurities, then drying the AgCl to obtain a solid residue. The dried AgCl can then be weighed to determine its mass and calculate the amount of chloride in the original sample of KClO3. This information can be used to determine the percent decomposition of KClO3.
AgCl.
AgCl is highly insoluble, as it is a precipitate.
Silver chloride
2 mol of AgCl to 1 mol BaCl2
When sodium chloride and silver nitrate are mixed, a metathesis reaction takes place. The silver ion becomes bonded to the chloride ion. Since silver chloride is insoluble, this substance precipitates out of solution.
1. Put the mixture in water and stir. 2. AgCl is not soluble, NaCl is soluble. 3. After filtering NaCl passes in solution and AgCl remain on the filter.
