Iron III chloride hexahydrate is a coordination compound with the formula FeCl6HO. In this compound, the central metal ion is Fe III , which has a +3 charge. The magnetic moment of a compound depends on the number of unpaired electrons in the central metal ion.The electronic configuration of Fe is [Ar] 3d^6 4s^2. When it forms the Fe III ion, it loses 3 electrons, leaving it with the electronic configuration [Ar] 3d^5. This means there are 5 unpaired electrons in the Fe III ion.To calculate the magnetic moment of the compound, we can use the formula: = n n+2 Bwhere n is the number of unpaired electrons and B is the Bohr magneton approximately 9.27 x 10^-24 J/T .For Fe III ion with 5 unpaired electrons: = 5 5+2 B = 5 7 B = 35 BTherefore, the magnetic moment of the compound Iron III chloride hexahydrate is approximately 35 B or around 5.92 B.
