1.   Water allows rusting of iron which is an oxidation process, that is, removal of electrons takes place during oxidation. 
Saline water contains salts like NaCl which behaves as an electrolyte. Salt concentration is measured in parts per million. Because of the number of dissociated ions, saline water conducts very well. As a result, number of electrolysis reactions take place which accelerate the rusting of iron in salt water.
Whereas in ordinary water no salts are present therefore, rusting of iron takes place slowly.
Thus, rusting of iron is quicker in saline water than in ordinary water.
2.    Life time of any cell depends upon ions present in cell. Ions are not involved in the overall cell reaction of mercury cell. Hence, mercury cell has a constant cell potential throughout its useful life.
