← Oxalic acid and acidified permanganate react slowly in a cold solution, but the pink colour fades faster after a few drops. What explains this?An iron tablet of mass 0.500 g is dissolved in acid, and the iron is all in the form Fe²⁺. It needs 17.4 mL of 0.0210 mol/L permanganate. The molar mass of iron is 55.85 g/mol. What is the percentage of iron by mass? →
