Question
A mixture of $H_2C_2O_4$ and $NaHC_2O_4$ is titrated with $NaOH$ and $KMnO_4$ separately. If $x$ moles of $NaOH$ and $y$ moles of $KMnO_4$ are required for the same amount of mixture, the ratio of moles of $H_2C_2O_4$ to $NaHC_2O_4$ can be found using:
Answer: A
💡 Solution & Explanation
Let moles be $a$ and $b$. <br>Acid-Base ($NaOH$): $H_2C_2O_4$ ($n=2$), $NaHC_2O_4$ ($n=1$). Eq = $2a + b = x$. <br>Redox ($KMnO_4$): Both $C_2O_4^{2-}$ units have $n=2$. Total Eq = $2(a+b) = 5y$ (since $KMnO_4$ has $n=5$).
