Ship wrecks at great depths are corroded by electrochemical reactions and by anaerobic bacteria

Explain that ship wrecks at great depths are corroded by electrochemical reactions and by anaerobic bacteria

  • The standard electrochemical corrosion of iron is slowed greatly at great depths due to:
    • Low temperatures.
    • Lack of oxygen.
  • However, shipwrecks at great depths also corrode through electrochemical reactions resulting from the actions of anaerobic bacteria.
