Which is the weight of A1 deposited at cathode when 1 ampere current is passed through molten AlCl ₃ for 9650 seconds? (At mass of Al =27 )
Options
- A3.0 g
- B9.0 g
- C13.6 g
- D0.9 g
Correct answer
D. 0.9 g
Step-by-step solution
aligned & Number of equivalents of Al deposited = I . t F & = 1 9650 96500 =0.1 & Number. Of equivalents = moles n _ factor & +3 AlCl ₃ Al _ factor =3 & 0.1= moles 3 & moles of Al =0.1 / 3 & mass of Al = 0.1 3 27=0.9 ~g aligned
