Answer:
Time take to deposit Ni is 259.02 sec.
Explanation:
Given:
Current A
Faraday constant
Molar mass of Ni
Mass of Ni g
First find the no. moles in Ni solution,
Moles of Ni
mol
From the below reaction,
⇆
Above reaction shows "1 mol of requires 2 mol of electron to form 1 mol of
"
So for finding charge flow in this reaction we write,
Charge flow C
For finding time of reaction,
Where charge flow
sec
Therefore, time take to deposit Ni is 259.02 sec.
