A metal's position in the galvanic series indicates its

  • A.melting point relative to other metals
  • B.thermal conductivity in the annealed state
  • C.tendency to corrode in a given environment
  • D.hardness and resistance to abrasion

Answer: C

The series ranks practical alloys by their measured potentials in a particular electrolyte, most commonly sea water, so it predicts which of a pair will be attacked. It differs from the electrochemical series in listing alloys and in accounting for passive films.
