Amount of (in grams) required to oxidize mole of to in acidic medium is ( of ): — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Meq of $Sn^{2+}$ ($n=2$) = $0.1 \times 2 \times 1000 = 200$. <br>Meq of $K_2Cr_2O_7$ ($n=6$) = $(W / 294) \times 6 \times 1000$. <br>$(W \times 6000) / 294 = 200 \Rightarrow W = (200 \times 294) / 6000 = 294 / 30 = 9.8$ g.
