Qualitative reactions for chloride, bromide, iodide anions.

Let’s write down qualitative reactions for chloride, iodide and bromide ions.
We write down the equation of reactions.
Qualitative reactions for chloride ion.
Cl- + AgNO3 = AgCl + NO3-.
When the chloride ion interacts with silver nitrate, the result is a white precipitate of silver chloride.
This precipitate dissolves on interaction with ammonia.
Qualitative reactions for bromide ions.
10Br- + 2MnO4 – + 16H + = 5Br2 + 2Mn2 + + 8 H2O.
When interacting with potassium permanganate, bromine is formed, which turns the solution yellow.
Qualitative reaction to iodide ion.
2I- + 2Fe3 + = I2 + 2Fe2 +.
When interacting with iron chloride or sodium nitrate, iodine is formed, which turns the solution yellow – brown.
