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
- A 70
- B 80
- C 60
- D 90
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 \(=0.965 \times 60 \times 60\) \[ =3474 \mathrm{C} \quad(\because Q=i \times t) \]…
