x moles of K\(_2\)Cr\(_2\)O\(_7\) oxidises 1 mole of ferrous oxalate, in acidic medium. Hence 'x' is:
- A \(1.5\)
- B \(0.5\)
- C \(1.0\)
- D \(2\)
Answer & Solution
Correct Answer
(B) \(0.5\)
Step-by-step Solution
Detailed explanation
In acidic medium, potassium dichromate acts as an oxidizing agent and its n-factor is \(6\). \(Cr_2O_7^{2-} + 14H^+ + 6e^- \rightarrow 2Cr^{3+} + 7H_2O\) Ferrous oxalate (\(FeC_2O_4\)) undergoes oxidation where both \(Fe^{2+}\) and \(C_2O_4^{2-}\) are oxidized.…
