How much silver is in a silver Battery?

What is the resonant frequency of silver?
Hi there, am reasearching colloidal/ionic silver and am actually investigating what this frequency is myself. This is the only mention sofar, will post more when I find something noteworty. Commercial silver product site http://www.guardian-silver-health-supplements.com/guardian-silver-supplement/ More specifically, Professor Rustum Roy of Penn State University engineered a specific size of the Guardian Silver elemental silver particle that resonates at 890 to 910 terahertz-the same frequency as blue germicidal lights used in hospitals for disinfection. The silver nano particle emits a specific magnetic resonance-890-910 terahertz-which is selectively destructive to pathogens. /Tommi
What do you mean by ESP?
what does e.s.p stand for on silver
Do you have Similes for robot?
The metal was as silver as a robot's head
Why is silver used to make mirrors?
Silver is used in mirror for the following reasons * Low density material so weight is comparatively lesser than the other white coloured metal. * Due to high reflection property of white colour, silver is used due to its non corrosive property. * so in general silver is used in glass on considering its strength, non corrosive, and reflection property.
What is the developing chemical in a pin hole camera photo?
Silver salts. Mainly silver halides.
What does STTP do in a photographic film developing formula?
In the processing of photographic films, plates or papers, the photographic developer (or just developer) is a chemical that makes the latent image Latent_imageonthe film or print visible. It does this by reducing the silver halides that have been exposed to light to elemental silver in the gelatin matrix. As a generalisation, the longer a developer is allowed to work, the greater the degree of reduction of the silver halide crystals to silver and therefore the darker the image.
Is film developing has to use fixer or only developer and stop can do the work?
You must use fixer. If you don't, the undeveloped silver halide will remain in the film, and you won't be able to get light through it--hence the negatives will be useless.
How does the developer bring out latent images on photographic papers and film?
Short version: the developer converts silver halide that was energized by light into black metallic silver. Unexposed halides are washed away by the fixer, leaving varying densities of black metallic silver in the black and white film. In the color process, intermediate steps replace the bms with dyes.
Is silver halides a metal or alloy?
Siver Halides are neither a metal or an alloy. They are a salt.
When a photographic film is exposed to light then salt on the film breaks down what meatel is formed?
The short answer is silver. In black and white film and print technology, the silver halides created by exposing the film to light in the camera or on paper under an enlarger, are reduced to silver by the developer and then the remaining halides are washed from the film during the fixing process. In some color photography, ALL of the silver is washed from the film and replaced by dyes introduced during the processing.
What do the chemicals on photography film react with?
You will have to be more specific: black and white? color negative? color slide? Polaroid instant film? Do you mean how do the developing chemicals act on film? Broadly speaking, "chemicals" has more to do with development whereas compounds would apply to film. Films are coated in silver halides. When the film is exposed it has what is called " a latent image'. It stays like that until it is developed. Once the film is developed the silver halides turn into black metalic silver halides. At this point we have both on the film and we have to removed the unexposed and undeveloped silver halides. This is done by fixing the film using in and acid mixture that removes the unexposed halides and stops any further developing of the film. The film is then washed until the chemicals are removed. It is then dried. With colour films there are three layer of emulsion. Each layer is sensitive to a particular colour. The process is basically the same as above except that after the silver halides have been processed the colour chemicals are released on each layer by the chemical process.
What property of ionic compounds explains why silver halides can be used in photography?
Silver halides absorb light to form elemental silver. This is the basis for the photographic film. This is an unusual reaction and is certainly not common to all ionic compounds. Silver halides are also unusually insoluble, again not a common property of ionic compounds. In fact silver halides have quite a lot of covalent character! I am sure teacher has something in mind but its certainly not in mine.
Which silver halide is most soluble?
Solubility of the silver halides decreases down the group.The solubilities of silver halides decreases down the periodic table:AgF :Ksp=205AgCl:Ksp=1.8×10−10AgBr:Ksp=5.2×10−13AgI :Ksp=8.3×10−17
What will react with alcoholic silver nitrate?
Alcoholic silver nitrate reacts with alkyl halides to form silver halide and alkyl nitrate compounds. This reaction is commonly used in organic chemistry to identify the presence of alkyl halides in a sample.
What happens when silver halides are exposed to light or radiation?
They turn black
What is use of hypo in photography?
It removes undeveloped silver halides from photographic emulsions. This leaves the silver behind, giving you a prnt that won't eventually turn black (because silver halides will eventually turn black on their own) or a negative light will pass through.
