Question

electric current pass through unknown aqouoes solution is 3amp salt of Pb mass is 2.972 A.WT=106 find n
​

Answer 1

Answer:

4

Explanation:

For reduction: $Pd^{n+}$ + ne → Pd

  $\frac{w}{E_{pd} }$  = $\frac{i X t}{96500}$

   $\frac{2.977}{106.4/n}$ =$\frac{3 X 1 X 60 X 60 }{96500}$ ⇒ "4"
