Fe(II) to Fe(III) 需要氧气。 应该没有displacement of halogen,因为dissolution。 |

这是一个REDOX REACTION.
2Fe^2+(aq)   +   Cl2(g)   =   2Fe^3+(aq)   +   Cl^ -(aq)
所以this reaction involve conversion of iron(2) to iron(3)。product 是看不到的,因为Fe2(Br)3 是soluble的。但颜色已经转变了。iron(2) bromide是浅青色的,慢慢变成了brown colour。 
observation: when yelow greenish gas dissolve in pale green solution, the colour of solution will turn brown colour.
