Question

One g equivalent of Na metal is formed from electrolysis of fused NaCl. No. of mole of Al from the fused Na3AlF6 with the same current passed is :

Options

A.1
B.3
C.1/3
D.2

Solution

Na+    +   e- →  Na(s)
1mole   1 Faraday
Al3+ + 3e- →  Al(s)
      1 Faraday 
No. of mole of Al = mole.
