What would be the concentration of kmno4 to titrate versus 0.05m ferrous ammonium sulphate?

To titrate 0.05 M ferrous ammonium sulfate, you would typically use a 0.05 M potassium permanganate (KMnO4) solution. The balanced chemical equation for the reaction is 5Fe(NH4)2(SO4)2 + 8KMnO4 + 24H2SO4 → 5Fe2(SO4)3 + 8MnSO4 + K2SO4 + 24(NH4)2SO4 + 16H2O.
