**(A):** The -factor of in acidic medium is 6. <br> **(R):** In acidic medium, is reduced to . — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Assertion:** One molecule of potassium dichromate accepts 6 electrons. Statement is true. <br>**Reason:** The half-reaction is $Cr_2O_7^{2-} + 14H^+ + 6e^- \rightarrow 2Cr^{3+} + 7H_2O$. Each of the two $Cr$ atoms changes from +6 to +3, resulting in a total transfer of 6 electrons per molecule.
