Expert Answer
Dear Student,
KMnO4 + FeS2 + CuS → Cu2+ + Fe3+ + SO2
n = 11 for FeS2 and n = 6 for CuS
Equivalents of KMnO4 = Equivalents of FeS2 + Equivalents of CuS
N × V / 1000 = (M × VFeS2 × n) / 1000 + (M × VCuS × n) / 1000
N × 20 / 1000 = [(10 × 1 × 11) / 1000] + [(20 × 1 × 6) / 1000]
N = 1(10 + 120) / 20 = 230 / 20 = 11.5 N
