When $X$ amperes of current is passed through molten ${A l C l}_{3}$ for 96.5 s. 0.09 g of aluminium is deposited. What is the value of X?

Options:

Answer:

Solution:

Current $i = ?$

Equivalent weight of $A l = \frac{27}{3} = 9$

$w = Z . i . t o r i = \frac{w}{Z . t} = \frac{0.09 \times 96500}{9 \times 96.5}$

= 10 A
