Will silver react with zinc nitrate?
What is stainless silver?
Silver, over time, is oxidised by air and loses its shine. Stainless silver is electoplated with nickel (as is stainless steel) to prevent the oxidation. Electroplating involves immersing the silver object in a solution of a nickel salt and applying a negative charge to the silver to attract the positive nickel ions in the solution to form a nickel coating on the silver.

On stereo speaker copper wire with a white stripewhich is the negative?
It depends on how the system is configured. When wiring speakers, I use the following conventions, positive side first: red/black copper / silver solid / striped If you're not sure, run a test tone through the speakers. If it sounds awful, then reverse the wiring. You will not damage the speakers by wiring them incorrectly, as long as you are wiring them to the stereo. If you do something daft like try to put them into a wall outlet you'll probably fry them. Not that you'd care since you'd be dead and your house would have burnt to the ground.

Asked in Chemistry
Chemical formula of silver sulphide?
Silver Sulphide or Silver Sulfide has a Chemical formula of Ag2S. Two Silver Atoms and One Sulfur atom. Silver ions are most commonly found in the Positive One (+1) state, while Sulfur is most commonly found in the Negative Two (-2) state; Therefore you need two silver atoms to balance one sulfur atom.
Asked in Photography
Why do pictures come out negative in film rolls?
Film works by absorbing the light that hits it. The more light that hits an area on the film (meaning the brighter that part of the scene is), the darker the film will get. Slide film, which produces a positive image, works the same way. You get a positive image by developing the film, producing a negative image in the exposed silver grains, then developing the film again in a different developer that works on the silver grains not exposed in the camera.
Is the large prong positive on a polarized plug?
Asked in Science
How does Photographic plate work?
The plate is covered in a light sensitive compound, containing Silver Halide crystals. When light falls on the Silver-halide, it causes the silver atoms to clump together. When developed with chemicals, the silver is left behind, causing dark areas where light has fallen. This makes a negative image, where light is dark and dark is light. To get a positive print, simply shine light through the developed plate onto paper covered in the same Silver-halide compound. After the same chemical process, the picture is reversed again giving the positive image.
Asked in Chemical Bonding
What is ionic precipitation?
This is the preparation of Insoluble Salts.Insoluble Salts can be made by precipitation. This involves mixing a solution that contains its Positive ions with another solution that contains its Negative ions, For example , insoluble silver chloride is precipitated when solutions of silver nitrate and sodium chloride solutions are mixed together.
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.

What danguerre for photography?
Daguerre was an early pioneer in photography, around 1840. The Daguerreotype process produced a positive image made on a silver plated copper plate. Because this is a positive image on a metal plate only one image could be made from each exposure. *** Some say it's a negative image that appears positive because of the way the light reflects off of the polished surface that is behind the exposed and developed silver halide. I subscribe to this definition for two reasons: if you hold a daguerrotype on an angle just right, you can see the negative image, plus the image is reversed just like it is in a negative. See http://en.wikipedia.org/wiki/Daguerreotype and http://www.camerapedia.org/wiki/Daguerreotype_Process for this opposing view.
