1. The Fe2+ content of iron tablets was determined by titration with a freshly standardised solution of potassium manganate(VII), KMN04. The equation for the titration reaction is 5Fe2+ + Mn04-+ 8H+ 5FE3+ + Mn2+ + 4H20 Maximum 5 iron tablets each is 0.065g of iron and 0.02 moldm potassium manganate (VII)(KMNO4) and 1 moldm aqueous sulfuric acid Describe how exactly 250 cm3 of Fe2+ solution was prepared from five iron tablets, each of mass 0.325 g in order to give a sensible titre. your calculations must be given
