150 ml M/10 Ba(MnO4)2 in acidic medium can oxidise what?

Answer 1

A lot of things but I'm not inclined to give you a laundry list. You can use the molarity to convert Eocell at 1M to 0.1M (the Nernst equation), then look in the voltage charts to see which will give a positive voltage with this oxidizing agent.

Answer 2

Not satisfied

Answer 3

150 ml 1 M Fe+
50 ml 1 M FeCro4

Answer 4

Good
