Prep. of tetratiodotin and its triphenylphosphine complex...
 

In the Andrews titration used to determine I- is the potassium iodate acting as a reducing or oxidising agent?

Also, what are the isomeric forms of (Ph3P)2SnI4....

Any help is greatly appreciated thanks..

potassium iodate has to be an oxidising agent.


for the isomers, draw out an octahedral arangement (six ligands attached to a central ion) with the six ligands and you will see that the two triphenylphosphine ligands can either be next to each other or opposite each other.

will that complex have a charge on it?

depends whether it's Sn(II) - yes, or Sn(IV) - no

K thanx!
