Question

Given the table of standard reduction values below, which substance is the strongest g agent and which is the strongest reducing agent? (If your answer is an ion, do not include a space between the symbol and the c e and do no. use superscripts. If your answer is a solid metal, do include a space between the symbol and the state indicator.) Au+ + e. Au (s) E"red = 1.692 V Cu2+ + 2e- Cu (s) E"red = 0.34 V Pb2+ + 2e- Pb (s) Eared =-0.1262 V Al3t + 3e- Al (s) E"red =-1.662 V Ca2+ + 2e- Ca (s) E"red =-2.868 V

Explanation / Answer

Lower the reduction potential higher the reducing power and higher the reduction potential higher the oxidizing power.

Here Ca (s) has lower potential hence strong reducing agent, while Au(s) has more reduction potential hence strong oxidizing agent.
