F.5 Chem

你錯左concept喇...
The following reaction is a redox reaction
AgI(aq)+cl2(aq)─→Agcl(s) + I2(g)

Iodide ions act as a reducing agent while chlorine is an oxidizing agent.
Actually chlorine is stronger oxidizing power than that of iodine.
Above the reaction, chlorine can oxidize iodide ions to gives iodine molecules.
So chlorine can react silver iodide to form silver chloride and iodine.

By comparing oxidizing power,
chlorine is strong oxidizing agent whereas iodine is weak oxidizing agent

By comparing reducing power,
iodide ion is strong reducing agent but chloride ion is weak reducing agent

I hope my answer can help you.

This reaction is a displacement reaction and a redox reaction
since Chlorine, having stronger oxidizing power
forming chloride ion
will displace the iodide ion out in AgI
Iodide ion act as a reducing agent
becomes iodine.

PS Chlorine is more reactive then Iodine
Chlorine has stronger oxidizing power than Iodine
Iodide ion is more unstable than Chloride ion.
