Redox Reactions in Titrimetry — Prelims Questions

25.0 mL of an aqueous solution of $\text{FeSO}_4$ required 20.0 mL of 0.02 M $\text{KMnO}_4$ solution in acidic medium for complete titration. The concentration of $\text{FeSO}_4$ in the solution is:

Which of the following statements is INCORRECT regarding redox titrations?

What is the n-factor of oxalic acid ($\text{H}_2\text{C}_2\text{O}_4$) when it reacts with $\text{KMnO}_4$ in acidic medium?

A 10.0 mL sample of $\text{H}_2\text{O}_2$ solution is titrated with 0.05 M $\text{KMnO}_4$ in acidic medium. If 15.0 mL of $\text{KMnO}_4$ is required, what is the molarity of the $\text{H}_2\text{O}_2$ solution?

In an iodometric titration, 20.0 mL of an oxidizing agent solution liberated iodine from an excess of KI solution. The liberated iodine required 15.0 mL of 0.1 M $\text{Na}_2\text{S}_2\text{O}_3$ solution for complete reaction. What is the normality of the oxidizing agent solution if its n-factor is 2?

Which of the following is NOT a suitable condition for a successful redox titration?

What is the normality of a 0.02 M $\text{KMnO}_4$ solution when used as an oxidizing agent in a neutral medium?
