As the above reactions are sensitive to light, they are used in black and white photography. It is seen that decomposition reactions require a source of energy in the form of heat, light, or electricity to decompose the compound involved. Hence, it can be concluded thatdecomposition reactions are endothermic in nature. Answer verified by Topp Black-and-white photographic chemistry: A reference This work is intended as a reference of black-and-white photographic chemistry. Included is a basic history of the photographic processes and a complete description of all chemicals used, formulas for the development and fixation process, and associated formulas such as cleaners, hardeners, and toners Components: Film Negatives consist of light sensitive. crystals of silver halide salts. These crystals consist of Silver Bromide (AgBr), Silver Iodide (AgI), or Silver Chloride (AgCl). Formation of the Latent Image in the camera and the dark room: When a photo is being taken a shutter opens up briefely or for or for a lenghty period of time. In black and white photography, the chemical Silver Bromide (or AgBr), which is a photosensitive compound, when exposed to sunlight or white light of any form and origin decomposes, and then forms Silver metal and Bromine gas. The balanced equation for this is as follows: Which is the equation used in black and white photography Brainly User One example of a photochemical reaction is the use of silver halide salts (eg silver chloride) in black and white photography. Silver chloride is sensitive to light and breaks down to form metallic silver, which appears black

From a light sensitive black and white film, how do we obtain a negative which is no more light sensitive and can be observed in broad daylight ? In 3 steps: (1) Exposure of the light sensitive emulsion followed by its processing, which are (2) the action of the developer agent and (3) the fixer agent Your question is not specific enough. Black and white, actually gray scale, photographic images can be produced digitally or chemically. B/W film and prints result from chemicals applied to a surface which react to light. That surface is typically.. The chemistry of photography is based on photosensitivity and reactions with light. The chemical processes that create a traditional photograph start inside the camera with the absorption of photons. However, photochemistry alone is not able to produce an image. Development is continued in the darkroom through chemical reactions involvin Q8:-The white solid compound A decomposes quite rapidly on heating in the presence of a black substance X to form a solid compound B and a gas C. When an aqueous solution of compound B is reacted with silver nitrate solution, then a white precipitate of silver chloride is obtained along with a potassium nitrate solution

Which reaction are used in Black and White photograph

Traditional black and white photography utilized a chemical process that has been observed since ancient times - that of the photo-sensitivity of silver (Ag) compounds. This ability was harnessed by the19th century photography pioneers by coating silver halides (molecules of Ag and halide gases) in an emulsion of gelatin onto a glass or plastic backer Black and white strips the image down to the basics. In a sense, black and white photography strips away all the extras, and forces you to think about things like contrast and emotion, in a way that isn't always be as crucial when you're shooting in color. Whether intentional or not, it can be easy to use color and props as a sort of crutch. which two reactions are used in black and white photography - Chemistry - TopperLearning.com | z61y3pkk Starting early can help you score better!

The above two reactions are used in black and white photography. Decomposition reactions are opposite of combination reactions. (c) Displacement reaction: The chemical reaction in which a more reactive element displaces a less reactive element from its salt solution is known as displacement reaction Silver salts are used in black-and-white photography. Owing to the value of silver, the ions left in developing solutions are often collected by precipitation reactions for recycling.A 4.3LJus developing solution was treated with an excess of sodium chloride, and a precipitate con of dry silver chloride was collected Photographic fixer is a mix of chemicals used in the final step in the photographic processing of film or paper. The fixer stabilises the image, removing the unexposed silver halide remaining on the photographic film or photographic paper, leaving behind the reduced metallic silver that forms the image.By fixation, the film or paper is insensitive to further action by light
