In the complex ion [Fe(CN)6]3-, what is the oxidation state of iron? (2023)
Step 1: Identify the complex ion, which is [Fe(CN)6]3-.
Step 2: Determine the charge of the CN- ligand, which is -1.
Step 3: Count the number of CN- ligands in the complex. There are 6 CN- ligands.
Step 4: Calculate the total negative charge from the CN- ligands: 6 ligands * -1 charge = -6.
Step 5: The overall charge of the complex ion is -3.
Step 6: To find the oxidation state of iron (Fe), set up the equation: Oxidation state of Fe + Total charge from CN- ligands = Overall charge of the complex.
Step 7: Substitute the values into the equation: Oxidation state of Fe + (-6) = -3.
Step 8: Solve for the oxidation state of Fe: Oxidation state of Fe = -3 + 6 = +3.
