Question

When $\text{X}$ 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?

• A. 10 A
• B. 20 A
• C. 30 A
• D. 40 A

Answer 1

Answer: (A)

Current $\text{i} \, =?$

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

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

= 10 A
