neutralisation reaction between iron and potassium manganate

Extracts from this document...


Introduction Titration is a method to find out how much acid would neutralize an alkali The following equation shows the neutralisation reaction between iron and potassium manganate i will be carrying out this reaction in my experiment 5Fe2+(aq) + MnO4- (aq) + 8H+ --> 5Fe+3(aq)+Mn+2(aq) + 4H2O(l) We made the ammonium sulphate solution with the concentration of 0.05moldm3 with the volume 250cm3 To calculate the molecular mass i added up all the elements, (Fe(NH4)2 (SO4)2 6H2O), the molecular ...read more.
