Question

why is PbCl$x_{123} 4$ a good oxidizing agent?

Answer 1

DUE TO INERT PAIR EFFECT THE HIGHER OXIDATION STATE IS STABLE . THEREFORE 4+ STATE IS STABLE AND SO 2+ STATE LOSSES 2 ELECTRONS AND GETS CONVERTED TO 4+ STATE , THIS PROCESS IS CALLED OXIDISATION. PbCl2 ODIXIDES ITSELF THEREFORE ITS A REDUCING AGENT. SO, THIS IS ALSO THE REASON FOR PbCl4 NOT BEING AN OXIDISING AGENT.
