How much charge in coulombs is required for the reduction of one mole of Al ³⁺ to Al?
Options
- A1.930 10⁴ C
- B2 895 10⁵ C
- C2 895 10⁴ C
- D1.930 10⁵ C
Correct answer
B. 2 895 10⁵ C
Step-by-step solution
Al ^ 3 * +3 e ⁻ Al 1 mole of electron =1 ~F =96500 coulombs 3 e ⁻=3 ~F =3 96500=2,89,500=2.895 10⁵ coulombs
