The volume of required to oxidize mL of in acidic medium is: — Redox Reactions and Volumetric Analysis Chemistry Question
Question
The volume of $0.1 M$ $KMnO_4$ required to oxidize $100$ mL of $0.2 M$ $H_2C_2O_4$ in acidic medium is:
Answer: A
💡 Solution & Explanation
Meq of $H_2C_2O_4$ ($n=2$) = $100 \times 0.2 \times 2 = 40$. <br>Meq of $KMnO_4$ ($n=5$) = $V \times 0.1 \times 5 = 0.5V$. <br>$0.5 V = 40 \Rightarrow V = 80$ mL.
