Question

Arrange these species by their ability to act as an oxidizing agent.  Best oxidizing agent  Poorest oxidizing agent  Ni2+, Mg2+, Zn2+, Au3+

censoratojk · Accepted Answer

Step 1  Given ionic species:  Ni2+, Mg2+, Zn2+, Au3+  Step 2  From the standard reduction potential data  Ni2++2e−⇒Ni  E∘=−0.26v  Mg2++2e−⇒Mg  E∘=−2.37v  Zn2++2e−⇒Zn  E−=−0.76v  Au3++3e−⇒Au  E∘=1.40v  Reduction potential more act as strong oxidining agent means it  Can take electrons from less reducetion potentid species  Based on this: best oxiding agent is Au3+  Poor oxiding agent: Mg2+  Oxidizing agent Capacity increasing order Mg2+&amp;lt;Zn2+&amp;lt;Ni2+&amp;lt;Au3+  Best oxidizing agent  Au3+  Ni2+  Zn2+ Poor oxigizing agent Mg2+
