What happens when silver is exposed to sunlight?
When light shines on the silver chloride/albumin emulsion the redox reaction happens more quickly than it does in the dark. Imagine now a sensitized sheet of paper, half of which is exposed to bright sunlight and the other half of which is covered up with an opaque card. The silver ions in the exposed area will be reduced to black metallic silver in a matter of minutes; the silver ion under the card will remain colorless or white. Imagine now that you remove the opaque card; what will you see? The half of the paper that was in the light will be black and the half that was in the dark will be white. This reversal of light and dark is referred to as a negative image. But as soon as you remove the opaque card from the sensitized paper, the formerly unexposed white half will begin to turn black. In order to fix the image, we need to remove the light-sensitive silver chloride. Just washing it in water won't do the trick because silver chloride is insoluble in water. The earliest photographic fixer consisted simply of a concentrated solution of sodium chloride, ordinary table salt: While certainly convenient, this reaction does not go very far; only some of the silver chloride is dissolved and the rest remains on the paper. More effective than salt is ammonia.
What is the precipitate color of silver nitrate and barium chloride?
Silver chloride (AgCl) gives a white precipitate. Silver Bromide (AgBr) also gives a white precipitate, though it's a slightly more creamy white than the precipitate formed by AgCl. Silver iodide (AgI) gives a pale yellow precipitate.
What is the grey deposit when mixing platinum chloride covered with a zinc strip?
The grey deposit formed when mixing platinum chloride covered with a zinc strip is likely metallic platinum. This reaction is known as a displacement reaction, where the more reactive zinc displaces the less reactive platinum from the platinum chloride solution. The platinum is then deposited as a solid grey layer on the surface of the zinc strip.
What color streak does silver have?
Silvery grey color :). BTW: Ur Welcome. you may think i spelt grey wrong but you can spell it 2 different ways :)
Why do clouds go grey when it rains?
Clouds appear grey when it rains because they become denser with water droplets, which scatter and absorb sunlight, making the clouds look darker. This increased density blocks more sunlight from passing through the cloud, giving it a grey appearance.
Why does white siver chloride turn grey in sunlight?
White silver chloride turns grey in sunlight due to a chemical reaction known as photo-reduction. When exposed to sunlight, silver chloride decomposes into silver metal and chlorine gas. This leads to the formation of gray-colored silver metal on the surface of the silver chloride.
What change in colour is observed when a silver chloride is left exposed to sunlight?
Silver chloride turns a gray or violet color when exposed to sunlight due to the formation of elemental silver.
Why silver chloride gray in sunlight?
Silver chloride turns grey in sunlight because of decomposition reaction. this decomposition reaction is called photoletic decomposition. 2AgCl gives Ag + Cl2 (silver (silver) (chloride) chloride)
What happens when silver chloride is left in sunlight for sometime?
When silver chloride is left in sunlight for some time, it will undergo a photochemical reaction that causes it to darken and eventually turn gray or black. This is due to the decomposition of silver chloride into elemental silver and chlorine gas upon exposure to light.
What happen when silver bromide is kept in sunlight?
When silver bromide is exposed to sunlight, it undergoes a chemical reaction wherein the silver bromide decomposes into silver metal and bromine gas. This reaction is utilized in analog photography to capture images on film.
What are some other reactions that depend on light?
Some reactions that depends upon light are:Silver chloride turns grey in sunlight .This is due to the decomposition of silver chloride into silver and chloride by light.Silver bromide also decomposes like silver chloride.These reactions are generally called photo decomposition reaction .These reactions are also use in black & white photography.
What happens when silver chloride is exposed to light?
Silver chloride undergoes a photochemical decomposition reaction in the presence of light, breaking down into elemental silver and chlorine gas. This reaction can be used in photography to develop images on film.

What type of reaction takes place when silver bromide is exposed to sunlight?
Photodecomposition reaction occurs when silver bromide is exposed to sunlight. The sunlight causes the silver bromide to decompose into silver and bromine atoms, leading to a color change from white to grey or black.
How to test chloride ion?
Add dilute nitric acid and silver nitrateResult - A white precipitateAdded:...... but be aware that Bromide and Iodide (and some other anions) will react almost accordingly. So it isn't too specific!However, if you look very closely, the bromide ion turns a cream coloured precipitate, and the iodide ion, a yellow precipitate. Silver chloride and -bromide will turn in grey black after some time exposed to light (photographic illuminate-reaction)
What is color of silver wire after chloride deposition on silver wire for the preparation of reference electrode?
The cholorided part will have a grey/purple to it. Some people describe it as a charcoal color.
What color is the Brooklyn bridge?
grey/silver (mostly)
