KMnO4 acts as an oxidising agent in acidic medium. The number of moles of KMnO4 that will be needed to react with one mole of sulphide ions in acidic solution is View Solution Volumetric titrations involving KMnO4, are carried out only in presence of dilute H2SO4 but not in the presence...
If the mass of nail used was 1.45g, calculate the number of moles of Fe2+ produced in the reaction. Quote My solution was 1.45 / 56 = 0.03 mol since 1 mol of Fe require 1 mol of H2SO4 to produce 1 mol of FeSO4. Why is this not accepted? Thanks. IMHO this is a correct approa...
