Potassium permanganate in acidic solution is used to titrate a solution of oxalic acid, with which it reacts according to
MnO4(aq) + 5H,C204(aq)+6H3O*(aq)→2Mn²*(aq) + 10CO2(g)+8H2O(1)
A potassium permanganate solution is prepared by dissolving 23.15 g of KMNO4 in water and diluting to a total volume of 1.000 L. A total of 20.92 mL of this solution is required to reach the
endpoint in a titration of a 150.0-mL sample containing H2C204(aq). Determine the concentration of H,C204 in the original solution.

Expert Solution

Step 1 Fundamental Step

This question demands the usage of concept of molarity.

Molarity is defined as the number of moles of the solute present per litre of solution. It is also known as molar concentration of solution and it's denoted by M. It's units are M or mol/L.

Now on diluting a solvent whose Molarity is M₁ to a molarity/concentration of M₂. The initial volume of solution was V₁and after dilution the volume became V_2.

So, the equation of dilution is represented by

M₁V₁ = M₂V₂

Here, we will use 1 for KMnO₄ nd 2 for H₂C₂O₄.

Now, we will find the molarity of KMnO₄, as it is given that 23.15g of KMnO₄is dissolved to form 1 liter of solution.
