The element that gains electrons/reduced is the oxidizing agent 


Recall the mnemonic for redox reactions:

Loss Electrons → Oxidation → Reducing Agent

Gain Electrons → Reduction → Oxidizing Agent


  • oxidation state for elements in natural state (s, l, g) = 0
  • oxidation state for ions = charge 


Zn(s) → Zn2+(aq) 

  • oxidation state increased from 0 to +2 → lost electrons → oxidation

Fe2+(aq) →Fe(s)

  • oxidation state decreased from +2 to 0 → gained electrons → reduction
