The decomposition of silver chloride is catalysed by?
The decomposition of silver chloride is catalyzed by light. When exposed to light, silver chloride decomposes into silver metal and chlorine gas.
What chemicals are in silver chloride?
Silver(+1 charged) and Chlorine(-1 charge)
What type of reactoin occur when sliver cholride is exposed to sun?
When silver chloride is exposed to sunlight, it undergoes a decomposition reaction to form silver metal and chlorine gas. This reaction is a photochemical reaction, meaning that it is initiated by light.
What change in colour is observed when silver chloride is left exposed to sunlight state the type of chemical reaction in this change.?
Silver chloride changes from white to gray or purple when exposed to sunlight, due to the decomposition of silver chloride into elemental silver and chlorine gas. This is a photochemical reaction, where light energy initiates the reaction.
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 halides are exposed to light or radiation?
They turn black
Why should silver chloride be protected from light will result be high or low if you don't protect your silver chloride?
Silver chloride is photosensitive, meaning it can decompose if exposed to light, leading to low yields and impurities in chemical reactions. If not protected, the quality of the silver chloride will be low, potentially affecting the accuracy and reliability of any experiments or processes in which it is used.

Is silver chloride used in photography?
Yes, silver chloride is used in photography as a light-sensitive chemical in the production of black-and-white photographic papers. When exposed to light, silver chloride undergoes a chemical reaction that forms an image on the photographic paper.
Why can you get a negative image when light reacts with silver chloride?
The light that makes the image on a film coated with silver chloride is absorbed by individual grains of solid silver chloride, and this absorption leaves the silver ions in an excited state, with more energy than the ions not exposed. The stronger the light, the more silver chloride grains in the image are exposed. When the exposed film is "developed", traditionally in a bath of sodium thiosulfate solution, the excited silver ions are reduced to metallic silver, which is black because it is so finely divided. Therefore the portions of the film that received the most light when forming the photograph become the darkest in the negative formed by development. When light is projected through the developed negative onto photosensitive print paper, the darkest areas of the negative allow very little light through them and the lighter ones allow more light, so that the lighter and darker areas are reversed again to form a positive image.
Why does the color of AGCL change?
The color of silver chloride (AgCl) can change due to various factors such as exposure to light, impurities present, or changes in temperature. When AgCl is exposed to light, a photochemical reaction can occur, leading to a change in color from white to gray or pale yellow. Other impurities or reactions can also lead to color changes in silver chloride.
What happens when silver halide particles are suspended in gelatin?
All I know is, they change their structure when exposed to light.
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.
