Question

A mixture of NaHC2O4 and KHC2O4·H2C2O4 required equal volumes of 0.2 N KMnO4 and 0.12 N NaOH separately. What is the molar ratio of NaHC2O4 and KHC2O4·H2C2O4 in the mixture?

Answer 1

The molar ratio of NaHC2O4 and KHC2O4·H2C2O4 in the mixture is 1:1.

Step-by-step explanation:

To determine the molar ratio between NaHC2O4 and KHC2O4·H2C2O4 in the mixture, we can use the concept of equivalent. Equivalent is a measure of the amount of substance that can undergo a chemical reaction.

In this case, equal volumes of 0.2 N KMnO4 and 0.12 N NaOH were required, which means that the number of equivalents of NaHC2O4 is equal to the number of equivalents of KHC2O4·H2C2O4. The molar ratio between NaHC2O4 and KHC2O4·H2C2O4 is 1:1.
