Given the following polarization curves for each metal/electrolyte, determine whether the metal is active or passive and the corrosion current. In each condition assume the worst case scenario

a) Fe in concentrated HNO3 b) Fe in dilute HNO3 c) Ni in neutral aerated solution d) Cr in aerated neutral solution e) Cr in deaerated acid (pH=0.56) f) Cr in aerated acid (pH=0.56) g) Ti in aerated acid (pH=0.56) h) Ti in deaerated acid (pH=0.56) i) Could an increase in fluid velocity from an aerated acid solution at pH=0.56 passivate iron or Cr?. explain. j) Would the corrosion of Fe due to dissolved oxygen change significantly when the acidity decreases from pH=0.56 to 7.0 ? explain a) Fe in concentrated HNO3 b) Fe in dilute HNO3 c) Ni in neutral aerated solution d) Cr in aerated neutral solution e) Cr in deaerated acid (pH=0.56) f) Cr in aerated acid (pH=0.56) g) Ti in aerated acid (pH=0.56) h) Ti in deaerated acid (pH=0.56) i) Could an increase in fluid velocity from an aerated acid solution at pH=0.56 passivate iron or Cr?. explain. j) Would the corrosion of Fe due to dissolved oxygen change significantly when the acidity decreases from pH=0.56 to 7.0 ? explain
