A sample (5.6 g) containing iron is completely dissolved in cold dilute HCl to prepare a 250 mL of solution. Titration of 25.0 mL of this solution requires 12.5 mL of 0.03 M KMnO4 solution to reach the end point. Number of moles of Fe²+ present in 250 mL solution is x × 102 (consider complete dissolution of FeCl₂). The amount of iron present in the sample is y% by weight. (Assume: KMnO4 reacts only with Fe²+ in the solution Use: Molar mass of iron as 56 g mol¹) The value of x is A sample (5.6 g) containing iron is completely dissolved in cold dilute HCl to prepare a 250 mL of solution.
