Q35 / 160 · TS EAMCET 2003 · Chemistry

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 $X$ ?

  • Correct answer
    A
    10 ampere
  • B
    20 ampere
  • C
    30 ampere
  • D
    40 ampere

Solution

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

Hence, the correct answer is option: 'A'.
