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 $Ni$
$1\,F$ deposits $1\,g$ equivalent of $Ni$ or $1/2\,mole$ of $Ni$
$\therefore \,F$ will deposit $\frac {1}{20}\,=\,0.05\,moles$ of $Ni$
