The reaction will be:

KI(aq) + Cl2 → KCl(aq) + I2

The Iodide ion, from the added potassium iodide solution, is substituted by the Cl- ion to then form KCl. The iodine produced will then turn the hexane layer pink.

我認為是 KI(aq) + Cl2 → KCl(aq) + I2,

Just a normal substitution reaction.

加油!! Good luck on ur exam :smile:

all the above should be in aqueous phase, and the equation is not balanced... tut tut:

2KI(aq) + Cl2(aq) → 2KCl(aq) + I2(aq)

but I do agree that iodine turn the hexane pink from colourless

To the OP, why are you doing GCE O level? I thought that was long outdated and replaced with GCSE?

He's in Malaysia, and they probably still do the 'O' levels there, just like most other former British colonies.
