Question
When 12,000 coulombs of electricity is passed through the electrolyte, 3.0 g of a metal of atomic mass 96.5 g/mol is deposited. The electro-valency of the metal cation in the electrolyte is
Options
A.+4
B.+3
C.+2
D.−4
Solution
$n_{eq} = \frac{Q}{F} \Rightarrow \frac{3}{96.5} \times n = \frac{12000}{96500} \Rightarrow n = 4$
