MCQ
A solution of $Ni(NO_3)_2$ is electrolysed between platinum electrodes using $0.1$ Faraday electricity. How many mole of $Ni$ will be deposited at the cathode?
  • A
    $0.20$
  • ✓
    $0.05$
  • C
    $0.10$
  • D
    $0.15$
✓

Answer

Correct option: B.
$0.05$
b
$1\,F$ deposits $1\,g$ equivalent of $Ni$ or $1/2\,mole$ of $Ni$

$\therefore \,F$ will deposit $\frac {1}{20}\,=\,0.05\,moles$ of $Ni$
