1.	3A current was passed through an aqueous solution of an unknown salt of `Pd` for 1hr. `2.977 g` of `Pd^(+n)` was deposited at cathode. Find n.
Answer» Correct Answer - `n =4` `Pd^(+n) +nE rarr Pd` `n_(Pd) = (2.977)/(106.4)` `n_(Pd) = 0.028` `n_(E) = 0.028 xx n` `= (0.0238 xx n xx 96500)/(3600) =3 [1=(q)/(t)]` `n = 4`
