Answer 2

Answer:

2.93 gm of Ni ions required = 0.0999 farads.

Explanation:

Since we know that in Nickel chloride, nickel valency is +2.

$Ni\rightarrow Ni^{+2} +2e^{-}$

we know the 1 mol of Ni contains = 58.6 gm...................(1)

1 mol of Ni contains = 2 faradays...........................(2)

from (1) and (2) we get,

58.6 gm of Ni requires 2 faradays.

So,

1 gm of Ni requires = $\frac{2}{58.6} = 0.0341 faraday$............(3)

We need to finds the farad for 2.93 gm of Ni ions fron melted Nicl2

So, multiply both sides 2.93 in equation (3) we get,

2.93 gm of Ni ions required = 0.0341 x 2.93 = 0.0999 farads.
