When \(X\) amperes of current is passed through molten \(\mathrm{AlCl}_3\) for \(96.5 \mathrm{~s}, 0.09 \mathrm{~g}\) of aluminium is deposited. What is the value of \(X\) ?
- A 10 ampere
- B 20 ampere
- C 30 ampere
- D 40 ampere
Answer & Solution
Correct Answer
(A) 10 ampere
Step-by-step Solution
Detailed explanation
Current \(i=\) ? Equivalent weight of \(\mathrm{Al}=\frac{27}{3}=9\) \(w=z i t\) \(i=\frac{w}{z t}=\frac{0.09 \times 96500}{9 \times 96.5}=10\) ampere
