A solution of permanganate is standardized by titration with oxalic acid, . To react completely with mol of oxalic acid required 37.02 mL of permanganate solution. The unbalanced chemical equation for the reaction in acidic solution is

Explanation:

Hello,

In this case, the undergone chemical reaction is:

In such a way, the acidic redox balance turns out:

Which leads to the total balanced equation as follows:

Thus, as the mass of oxalic acid is not given, one could suppose a value of 1 g (which you can modify based on the actual statement) in order to compute the oxalic acid moles as shwon below:

Whereby the molality results:

Remember you can modify the oxalic acid mass as you desire.

Best regards.

i believe the answer is true.
