Can someone explain the halogens and the cyclohexane thing ik that
Cl- + kbr + = kcl +br2 this is orange/red
Cl- +ki+ = kcl2 +i2 this is pink?
Br- +ki + = kbr + i2 this is also pink?
Iodine doesnt react its less reactive = no colour
Correct me if I'm wrong and i dont get the cyclohexane and the colour afterwords

Cyclohexane is a non-polar solvent and dissolves the halogens in their molecular form allowing their true colour to be seen.

If you shake an aqueous solution the halogen is extracted into the non-polar solvent and the colour can be seen more clearly.

Iodine is dark purple
Bromine is orange
Chlorine is pale green
Astatine is sky blue pink ...



... OK, I made the last one up.
