How many moles of are required to oxidize mole of in acidic medium? (Answer as simplest fraction, fi — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Step 1:** $n$-factor $K_2Cr_2O_7 = 6$. <br>**Step 2:** $n$-factor $FeC_2O_4 = 3$ ($Fe^{2+} \rightarrow Fe^{3+}$ is 1, $C_2O_4^{2-} \rightarrow 2CO_2$ is 2). <br>**Step 3:** $6 \times n = 3 \times 1 \Rightarrow n = 0.5 = 1/2$. <br>**Step 4:** $x=1, y=2$. Result $x+y = 3$.
