Answer:
Balanced net ionic equation;
2MnO₄⁻ + 16H⁺ + 5C₂O₄²⁻ → 2Mn²⁺ + 8H₂O + 10 CO₂
Explanation:
- This is an example of a redox titration where acidified potassium permanganate (KMnO₄) is titrated against oxalic acid (H₂C₂O₄).
- A redox reaction is a type of reaction that involves both reduction and oxidation.
- One reactant of the reaction gains electrons(reduction) while another loses electrons(oxidation).
- During the redox reaction, H⁺/KMnO₄ undergoes reduction while the oxalic acid undergoes oxidation.
- Therefore, KMnO₄ is the oxidizing agent while H₂C₂O₄ is the reducing agent.
- The net ionic reaction will be;
2MnO₄⁻ + 16H⁺ + 5C₂O₄²⁻ → 2Mn²⁺ + 8H₂O + 10 CO₂
- From the reaction, MnO₄⁻ is reduced to 2Mn²⁺ while C₂O₄²⁻ is oxidized to CO₂.
- Therefore, two moles of KMnO₄ will react with 5 moles of oxalic acid.
To find solubility, we need calculate how much potassium sulfate will be dissolved at 100 g of water.
12 g potassium sulfate ------ 75 g water
x g potassium sulfate --------100 g water
x=12*100/75 = 16g
So, solubility of potassium sulfate at 60⁰ C is 16 g potassium sulfate per 100 g of water.
