What does halide test include

Uses solution of silver nitrate, its soluble in water and it contains silver ion Ag+, and nitrate ion NO₃^-

What happens if we mix silver nitrate solution with solution containing halide ion

Silver ion reacts with the halide ion to form silver halide. Silver halide precipitate is formed, the colour of silver halide can be used to determine the halide ion we started with

What does reacting silver nitrate with chloride ion produce

White precipitate of silver chloride.

What does reacting silver nitrate with bromide ion produce

Cream precipitate of silver bromide.

What does reacting silver nitrate with iodide ion produce

Forms a pale yellow precipitate of silver iodide.

What will precipitate of silver chloride / bromide do in dilute aqueous ammonia

It will redissolve if its silver chloride

Precipitate of silver bromide will not redissolve.

Silver iodide does not redissolve in concentrated or dilute ammonia.

What will happen to silver bromide if concentrated aqueous ammonia is added

It will redissolve.
