1. A student carried out a redox titration to find the amount of iron in an iron tablet. They followed the following steps.

1. Crush the iron tablets using the pestle and mortar

2. Transfer the crushed tablets to a weighing boat and measure their combined mass

3. Empty the crushed tablets into the small beaker and reweigh the weighing boat Add 100 cm³ of 1.5 mol dm⁻³ of sulfuric acid to the small beaker and stir to dissolve the tablet

4. Filter the solution (to remove any undissolved solids) into the volumetric flask. Rinse the beaker with more sulfuric acid and add the washings to the volumetric flask. Make up to the 250 cm³ mark with distilled water

5. Pipette 25.0 cm³ of this solution into the conical flask

6. Titrate the iron(II) solution with 0.005 mol dm^-3 potassium manganate(VII) solution until the mixture has just turned pink

7. Record your results in an appropriate format and repeat the titration until concordant results are obtained

The unbalanced equation for the reaction is shown below.

__MnO₄^- (aq) + __H⁺ (aq) + __Fe²⁺ (aq) → __Mn²⁺ (aq) + __H₂O (l) + __Fe³⁺ (aq) 

Balance the equation for the titration.
