We are being asked to rank the following species by their ability to act as an oxidizing agent Au3+, Ca2+, Pb2+, Fe2+
Oxidizing agents are the species that are being reduced in a redox reaction. Recall the mnemonics LEO GER.
The strongest oxidizing agent would be the element that would be easily reduced or most likely to gain an electron.
Rank these species by their ability to act as an oxidizing agent. Au3+, Ca2+, Pb2+, Fe2+
