Left : Iron(III) chlorideRight : Iron(II) chloride

Confirmatory test for Fe3+ ion :Iron(III) ion in alkali solution (NaOH /NH3 solution)

Confirmatory test for Fe2+ :Iron(II) ion in alkali solution (NaOH / NH3 solution)

Oxidizing agent :Acidified potassium dichromate(VI) solution,K2Cr2O7

Oxidizing agent :Acidified potassium manganate(VII) solution, KMnO4

Oxidizing agent :Chlorine water

Oxidizing agent :Bromine water

Iodine solution

Test to confirm presence of halogens :Halogens in cyclohexane (Upper layer)From left : chlorine, bromine, iodine

Halide solutions

From left : magnesium, Mg, iron, Fe, copper, CuMost metals are grey solids except for copper, it is brown solid.

Increasing order of good reducing agent : Cu Fe Mg

Copper(II) sulphate solution

The solution is blue because of the presence of copper(II) ion, Cu2+
