Chemistry · Secondary 4 · Hard · Titration calculations

A student titrates 25.0 cm³ of 0.120 mol/dm³ iron(II) sulfate solution with acidified potassium manganate(VII) solution. The equation is:

5Fe^{2+} + MnO_4^- + 8H^+ \rightarrow 5Fe^{3+} + Mn^{2+} + 4H_2O

.

If 18.0 cm³ of

MnO_4^-

solution is required, what is the concentration of the

MnO_4^-

solution?
