**(A):** mole of can oxidize moles of ions in acidic medium. <br> **(R):** The -factor of is 6 and t — Redox Reactions and Volumetric Analysis Chemistry Question
Question
**(A):** $1$ mole of $K_2Cr_2O_7$ can oxidize $6$ moles of $Fe^{2+}$ ions in acidic medium. <br> **(R):** The $n$-factor of $K_2Cr_2O_7$ is 6 and that of $Fe^{2+}$ is 1.
Answer: A
💡 Solution & Explanation
**Assertion:** Equivalents of OA = Equivalents of RA. $1 \times 6 = 6 \times 1$. True. <br>**Reason:** $K_2Cr_2O_7 \rightarrow 2Cr^{3+}$ ($n=6$) and $Fe^{2+} \rightarrow Fe^{3+}$ ($n=1$). The ratio of moles is the inverse of the ratio of $n$-factors. True and explains the Assertion.
