(i) When aqueous silver nitrate is added to potassium bromide the following reaction takes place:

AgNO3 + KBr = AgBr↓ + KNO3.

Silver bromide is a light yellow precipitate that is formed by this reaction. When ammonia is added, it dissolves and the solution becomes transparent.

(ii) When concentrated sulphuric acid is added to a small amount of solid potassium iodide the following reaction takes place:

KI + H2SO4 = KHSO4 + I2 + H2S + H2O

Iodine formes violet precipitate; hydrogen sulfide is colorless, yet it has a unique smell.
