Chemical Equation is:
2KMnO4 + 3H2SO4 -----> K2SO4 + 2MnSO4 + 3H2O + 5[O]
{ 2FeSO4(NH)42SO4.6H2O + H2SO4 + [O] ------> Fe2(SO4)3 + 2(NH4)SO4 + 3H2O } MULTIPLY BY 5
BY ADDING BOTH EQUATIONS:
2KMnO4+8H2SO4+10FeSO4(NH4)2SO4.6H2O--->K2SO4+2MnSO4+5Fe2(SO4)3+10(NH4)2SO4+18H2O
End point is:colorless to light pink
