What is the oxidation state of iron in the complex [Fe(CN)6]3-?

Step 1: Identify the overall charge of the complex [Fe(CN)6]3-. The charge is -3.
Step 2: Determine the charge of each cyanide (CN) ligand. Each CN has a charge of -1.
Step 3: Since there are 6 cyanide ligands, calculate the total charge contributed by the cyanides: 6 CN x -1 = -6.
Step 4: Set up the equation to find the oxidation state of iron (Fe). Let the oxidation state of Fe be x. The equation is: x + (-6) = -3.
Step 5: Solve the equation: x - 6 = -3. Add 6 to both sides: x = -3 + 6.
Step 6: Calculate the value: x = +3. Therefore, the oxidation state of iron in the complex is +3.
