For the oxidation of \(0.2 \mathrm{M} \mathrm{FeSO}_4\) solution 0.965 amperes current is passed through it for 1 hour. The volume of the solution that is oxidised in \(\mathrm{mL}\) is

  1. A 70
  2. B 80
  3. C 60
  4. D 90
Verified Solution

Answer & Solution

Correct Answer

(D) 90

Step-by-step Solution

Detailed explanation

The equation is \[ \mathrm{Fe}^{2+}+2 \mathrm{e}^{-} \longrightarrow \mathrm{Fe} \] 1 mole is deposited by \(2 \times 96500^{\circ} \mathrm{C}=193000^{\circ} \mathrm{C}\) The charged supplied \(=0.965 \times 60 \times 60\) \[ =3474 \mathrm{C} \quad(\because Q=i \times t) \]…
