0.1 mole Ni is obtained on electrolysis of NiSO_(4) solution in neural solution, how much faraday electricity should be pass through the cell ?

Answer»

1F
0.1 F
0.2 F
0.01 F

Solution :`NiSO_(4) to NI^(2+)+SO_(4)^(2-)`
`Ni^(2+)+2e^(-) to Ni`
So, 1 mole Ni is OBTAINED by 2F
Then 0.1 mole Ni is obtained by
`=(0.1" mole"xx2F)/(1" mole")=0.2F`
