Which silver halide is most stable?

Although most silver halides involve silver atoms with oxidation states of +1 (Ag+), silver halides in which the silver atoms have oxidation states of +2 (Ag2+) are known, of which silver(II) fluoride is the only known stable one.

Which halide of silver is used in photography?

Silver chloride, silver bromide (AgBr) and silver iodide (AgI) are the three silver “halide” compounds used in photography.

Which silver halide is most sensitive to light?

Since silver bromide, AgBr, and silver iodide, AgI, react similarly, all three of these silver halide salts are used in making photographic films and plates. Both the bromide and iodide are less soluble in water and more sensitive to light than the chloride.

Why are silver halides used in photography?

Silver halides are used in photography because they are photosensitive as they react with light to form the image, silver halides being reduced to silver.

How are silver halides used in photographic paper?

Silver halides are used in photographic film and photographic paper, including graphic art film and paper, where silver halide crystals in gelatin are coated on to a film base, glass or paper substrate.

Which is the most stable silver halide in the world?

Although most silver halides involve silver atoms with oxidation states of +1 (Ag + ), silver halides in which the silver atoms have oxidation states of +2 (Ag 2+) are known, of which silver (II) fluoride is the only known stable one. Silver halides are light-sensitive chemicals, and are commonly used in photographic film and paper.

What are the grain sizes of silver halides?

Silver-halide grain sizes vary from about 10 nanometers for the ultra-fine-grain holographic emulsions to a few micrometers for highly sensitive photographic emulsions (Table 1). Table 1. Silver halide emulsion grain sizes Silver salts are only sensitive to UV light, violet, and deep blue light.

Can a silver halide be sensitive to green light?

Orthochromatic emulsions are sensitive to green light. If the material has been sensitized to both green and red light, it is said to be panchromatic. In the following, silver halide materials manufactured by photographic and holographic companies are described.
