The image on an exposed and developed photographic film is due to

A

`AgBr`

B

`[Ag(C_(2)O_(3))_(2)]^(3+)`

C

`Ag`

D

`Ag_(2)O`.

Text Solution

Verified by Experts

The correct Answer is:
C
Quinol developer (a reducing agent) reduces AgBr to Ag.
`2AgBr^(+)(s)+2OH^(-)(aq)+C_(6)H_(5)(OH)_(2)(aq)to2Ag(s)+2H_(2)O+C_(6)H_(4)O_(2)(aq)+2Br^(-)(aq)`
Where `AgBr^(+)` represents a molecules of AgBr exposed to light.

Photography is based on the nature of silver halides. Except AgF, the silver halides are photosensitive. These undergo decomposition in light and turn black due to formation of free silver. 2AgBroverset(light)to2Ag+Br_2 The photography films are prepared by adding 20% aqueous solution of AgNO_3 to NH_4Br solution containing gelatic. When such a film is exposed, emulsion gets affected and a latent image is formed on the film. When this exposed film or plate is dipped ina developer which contains a reducing agent, the part affected most during exposure are reduced to the maximum. The image becomes visible. It is called a negative. The remaining sensitive emulsion on the negative is removed by dissolving it in hypo solution (fixer). Fihnally, a positive of the nagative already prepared is made on silver bromide paper. Q. The compound formed on the unexposed photographic film or plate is

The light sensitive compound on most photographic films is silver bromide AgBr. A film is exposed when the light energy of dissociation of AgBr is 10^(5)Jmol^(-1) . For a photon that is just able to dissociate a molecule of AgBr, the photon energy is
