Electrochemical series ranks metals by reducing ability; used to predict spontaneity of redox reactions and corrosion susceptibility.

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Input two half-reactions
  2. 2Look up standard reduction potentials
  3. 3Calculate cell potential: E°_cell = E°_cathode - E°_anode

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Zn + Cu²⁺: E° = 0.76 - (-0.76) = 1.52 V (spontaneous)
ଫଳ
Opposite reaction non-spontaneous (unless forced)

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Confusing oxidation and reduction half-reactions
  • Using wrong sign convention

What's the relationship to corrosion?

Metal higher in series (more negative) acts as anode, corrodes preferentially.
