A ferrous sulfate (BP) [FeSO4151.9g/mol] sample was analysed by titration using ammonium cerium (IV) nitrate (NH4)2Ce(NO3)6. The result shown 0.4980g of this sample used 25.50 ml 0.110M ammonium cerium (IV) nitrate. The BP specifies that ferrous sulfate material should contain not less than 86.0% and not more than 90.0% of FeSO4 Does the sample comply with the British Pharmacopoeia specification? A. The sample contains 85.6% ferrous sulfate thus does not comply with the British Pharmacopoeia specification B. The sample contains 85.6% ferrous sulfate thus complies with the British Pharmacopoeia specification C. The sample contains 86.0% ferrous sulfate thus complies with the British Pharmacopoeia specification D. The sample contains 89.0% ferrous sulfate thus complies with the British Pharmacopoeia specification E. The sample contains116.9% ferrous sulfate thus does not comply with the British Pharmacopoeia specification How do you work this out ?
