Silver nitrate and copper - phrase

When a copper coin is dipped in the solution of silver nitrate, it shows a lustre on its surface. Explain this process with the help of chemical equation. Explain this process with the help of a chemical equation. Solution Show Solution Copper is more reactive than silver. Therefore, copper displaces silver from its salt solution, silver nitrate. The glittering white deposit of silver metal is formed on the copper coin. Hence, when a copper coin is dipped in the solution of silver nitrate, it shows a lustre on its surface after some time. silver nitrate and copper.

Film basics[ edit ] Layers of 35 mm color film: 1. Film base; 2. Subbing layer; 3. Red light sensitive layer; 4. Green light sensitive layer; 5. Yellow filter; 6. Blue light sensitive layer; 7. UV Filter; 8.

Protective layer; 9. Visible silver nitrate and copper exposing film. There are several types of photographic film, including: Print film, when developed, yields transparent negatives with the light and dark areas and colors if color film is used inverted to their respective complementary colors. This type of film is designed to be printed onto photographic paperusually by means of an enlarger but in some cases by contact printing. The paper is silver nitrate and copper itself developed. The second inversion that results restores light, shade and color to their normal appearance.

Color negatives incorporate an orange color correction mask that compensates for unwanted dye absorptions and improves learn more here accuracy in the prints. Although color processing is more complex and temperature-sensitive than black-and-white processing, the wide availability of commercial color processing and scarcity of service for black-and-white prompted the design of some black-and-white films click are processed in exactly the same way as standard color film.

Color reversal film produces positive transparenciesalso known as diapositives. Transparencies can be reviewed with the aid of a magnifying loupe and a lightbox.

Expert Answer

If mounted in small metal, plastic or cardboard frames for use in a slide projector or slide viewer they are commonly called slides. Reversal film is often marketed as "slide film". Large-format color reversal sheet film is used by some professional photographers, typically to originate very-high-resolution imagery for digital scanning into color separations for mass photomechanical reproduction.

Photographic prints can be produced from reversal film transparencies, but positive-to-positive print materials for doing this directly e.

Conventional black-and-white negative film can be reversal-processed to produce black-and-white here, as by dr5 Chrome. Black-and-white transparencies may also be produced by silver nitrate and copper negatives onto special positive print film, still available from some specialty photographic supply dealers. The amount of exposure variation that a given film can tolerate, while still producing an acceptable level of quality, is called its exposure latitude. Color print film generally has greater exposure latitude than other types of cppper.

Additionally, because print film must be printed to be viewed, after-the-fact corrections for imperfect silver nitrate and copper are possible during the printing process. Plot of image density D vs. Changing the emulsion properties or the processing parameters will move the curve to the left or right.

Changing the exposure will move along the curve, helping to determine what exposure is needed for a given film. Note the coppee response at the far left "toe" and right "shoulder" of the curve. A dark image on the negative is of higher density than a more transparent image. Most films are affected by the physics of silver grain activation which sets a minimum amount of light required to expose a single grain and by the statistics of random grain activation by photons.]
