Calculate the weight of $A l$ deposited when a current of 5 Faradays is passed through a solution of $A l^{+ + +}$ ions, (The atomic weight of $A l$ is 27)

Options:

Answer:

Solution:

$A l^{3 +} + 3 e^{-} \to A l$
$E_{A l} = \frac{27}{3} = 9$
$W_{A l} = E_{A l} \times N o . o f f a r a d a y s$
$= 9 \times 5 = 45 g m$ .
