Passage II 
Accidently chewing of a stray fragment of aluminium foil can cause a sharp tooth pain if the aluminium comes in contact with an amalgam filling. This filling, an alloy of silver, tin and mercury acts as the cathode (of a tiny galvanic cell), the aluminium as anode and saliva (of mouth) serves as electrolyte. When the aluminium and the filling come in contact, an electric current passes from aluminium to the filling, which is sensed by a nerve in the teeth.
                         
Q.
Net reaction taking place when amalgam is in contact with aluminium foil is
  • a)
  • b)
    4AI + 3O2 + 12H+ → 4AI3+ + 6H2O
  • c)
    4AI + 3O2 → 2AI2O3
  • d)
    2H2 + O3 → 2H2O
Correct answer is option 'B'. Can you explain this answer?
