Why is `AgBr` used in photography ?

Text Solution

Verified by Experts

The correct Answer is:
Out of all silver halidas, `AgBr` is most sensitive to light and under goes photo reduction to metallic silver instantaneously on exposure to light.
`2AgBrto2Ag+Br_(2)`
Unexposed `AgBr` can be dissolved out in hypo `(Na_(2)S_(2)O_(3))` solution.
`AgBr+2Na_(2)S_(2)O_(3)toNa_(3)[Ag(S_(2)O_(3))]+NaBr`.
