The part of the silver halide crystal that is most affected by light when film is exposed is the surface. More specifically, any sensitivity specks that can become metallic silver.
To form an insoluble silver halide.
The presence of halide ions
Silver salts (AgCl)
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
Tarnish.
The "salt" you are referring to is actually called silver-halide and are more commonly known as "silver salts". When silver-halide crystals are exposed to light, they form a compound known as "metallic silver"
Silver Halide Silver iodide

All I know is, they change their structure when exposed to light.
To form an insoluble silver halide.
The product is a silver halide insoluble in water.
The larger the silver halide crystals are, the higher the films speed rating will be. The film will also be easier to overexpose.

A silver salt, more specifically a silver halide.
