Please show how to find moles of
KMnO4 added, moles of Fe3+, mass of
Fe3+, and mass percent of Fe3+
For my standardization of
KMnO4 the average molarity was 2.11x10-2M I'm
not sure if that's needed to solve
a)
Balanced net ionic equation for the redox reaction of
Fe2+and
MnO4-: 5Fe+2+
MnO4-2+
8H+Þ
5Fe+3+Mn+2+ 4H2O
b)
