When making photographic film, silver nitrate is treated with halide salts of sodium or potassium to form insoluble silver halide in situ in photographic gelatin, which is then applied to strips of tri-acetate or polyester. AgNO3 + NaCl -------->AgCl(s) + NaNO3 .
Silver salts are salts containing the cation of silver: silver nitrate, silver chloride, silver iodide, silver sulfate etc.
