Corrosion at Depths Shipwrecks and Salvage > Predictions of slow corrosion at great depths were apparently incorrect Students learn to: explain that ship wrecks at great depths are corroded by electrochemical reactions and by anaerobic bacteria describe the action of sulfate reducing bacteria around deep wrecks explain that acidic environments accelerate corrosion in non-passivating metals Students: perform a first-hand investigation to compare and describe the rate of corrosion of metals in different acidic and neutral solutions Extract from Chemistry Stage 6 Syllabus (Amended October 2002). © 2009, Board of Studies NSW.
