Question

Which complex of silver is formed during fixing of photographic
plates ? 180

Answer 1

Explanation:

the silver halides are being used for making the black and white photographs.

eg. sliver bromide. silver chloride.etc

Answer 2

In photography, a photographic plate is covered with silver halide crystals that are light-sensitive. The process is as follows:

• When the plate is exposed to light, some of the silver halide crystals conduct a chemical reaction and produce silver atoms as a result of the light energy. A visible image can then be created from the resulting metallic silver.
• Making the image permanent requires the fixing process. During fixing, the leftover silver halide crystals that were not exposed to light are dissolved using a solution containing a reducing agent, such as sodium thiosulfate (hypo). Only the metallic silver created during the exposure process is left behind, leaving a lasting impression on the plate.
