Text Solution

AI Generated Solution

To write the balanced reaction of the titration of potassium permanganate (KMnO₄) with oxalic acid (C₂H₂O₄) in the presence of sulfuric acid (H₂SO₄), we need to consider the redox nature of the reaction. Here’s how to derive the balanced equation step by step: ### Step 1: Identify the Reactants and Products The reactants in this titration are: - Potassium permanganate (KMnO₄) - Oxalic acid (C₂H₂O₄) - Sulfuric acid (H₂SO₄) ...

What is incorrect about the reactions of KMnO_(4) and oxalic acid

Amount of oxalic acid present in a solution can be determined by its titration with KMnO_(4) solution in the presence of H_(2)SO_(4) . The titration gives unsatisfactory result when carried out in the presence of HCl , because HCl :

Volumetric titrations involving KMnO_(4) , are carried out only in presence of dilute H_(2)SO_(4) but not in the presence of HCI or HNO_(3) This is because oxygen produced from KMnO_(4) + dil: H_(2)SO_(4) , is used only for oxidizing the reducing agent. Moreover, H2SO4 does not give any oxygen of its own to oxidize the reducing agent. In case HCI is used, the oxygen produced from KMnO_(4) + HCI is partly used up to oxidize HCI and in case HNO_(3) is used, it itself acts as oxidizing agent and partly oxidizes the reducing agent. KMnO_(4) , in various mediums gives following products Mn^(7+)overset(H^(+))toMn^(2+) Mn^(7+)overset(H_(2)O)toMn^(4+) Mn^(7+)underset(OH^(-))toMn^(6+) QThe number of moles of KMnO_(4) that will be needed to react with one mole of sulphite in an acidic solution is

A solution of 0.2 g of a compound containing Cu^(2+) "and" C_(2)O_(4)^(2-) ions on titration with 0.02 M KMnO_(4) in presence of H_(2)SO_(4) consumes 22.6 mL of the oxidant. The resultant solution is neutralized with Na_(2)CO_(3) acidified with dil. acetic acid and treated with excess KI. The liberated iodine requires 11.3 mL of 0.5 M Na_(2)S_(2)O_(3) solution for complete reduction. Find out the mole ratio of Cu^(2+) "to" C_(2)O_(4)^(2-) in the compound. Write down the balanced redox reactions involved in the above titrations.
