TO prevent the siver halides from decomposition...
as when it comes in contact of light the photo decomposition takes place.....

Why silver chloride storage in dark colour bottle?
Silver chloride is light sensitive. Light photons break the salt down into silver metal and chlorine gas. Using a dark bottle protects the salt from the light that would degrade the sample.
Could you say that the dark image on the photographic film is due to fluorescence why?
no, photographic films contains silver iodide which converts to gray-black metallic silver via photo reduction. Photo reduction is a light-dependent reaction which converts solar energy to chemical energy. when UV rays or visible light (basically sun rays) interacts with the silver chloride in the photographic film, photo reduction takes place. try pouring some silver chloride on a piece of white cloth, then leave it out in the sun, the area where the silver chloride is exposed to the sun will become dark coloured.

Is iron chloride is a coloured compound?
It depends on the viewing angle: by reflected light the crystals appear dark green, but by transmitted light they appear purple. they also change colour depending on whether they are dry crystals (yellow) or have water attached (green).
How can you test a solution for the presence of silver ions?
By using sulphur- a drop of heated liquid sulphur should be applied to the metal, which will create a dark patch of silver sulphide if the metal is pure silver (this is easily wiped off again). It is also possible to do this test by applying the combined flames from two lighted matches to the metal, but in this case the sulphide mark will NOT be removable.
What color do you get when you mix silver and black?
If you mix silver and black you get pewter.

Does a dark coloured tin heat up faster than a silver one?
If there is light on them the dark one will heat up faster because the dark one is absorbing light while the silver one is reflecting it away.
Why do you save silver chloride in dark bottle?
Normal daylight or artificial indoor light can cause reduction of the silver ions in silver chloride to metallic silver.Because on exposure to light it turns into silver metal and elemental chlorine. This reaction is the basis of photographic films.
What is dark colored and light colored?
Black is dark coloured and white is light coloured
Why are there silver residues on photos?
Photographic paper reacts with light because of the photochemistry of silver bromide and chloride. The silver residue is on the paper because that is what is actually reacting with the light to form a dark spot.
What colour is the Piccadilly line?
The Piccadilly line in the London underground is dark blue.
Do Chinese girls have dark coloured vagaina?
no
Is the dark parts of a silver neckless physical or chemical change?
The dark parts of a silver necklace are evidence of a chemical change called tarnishing, or oxidation. It is due to the reaction between silver and oxygen. The best way to store your silver jewelry is in sealed plastic bags.
Is crude oil thick and dark coloured?
Crude oil is thick and black coloured.......
What was the skin colour of draupati in Mahabharata?
She was dark coloured.
