What is the common oxidation state of iron in FeCl3? (2023)
  • Step 1: Identify the compound, which is FeCl3.
  • Step 2: Recognize that Cl (chlorine) typically has an oxidation state of -1.
  • Step 3: Since there are 3 chlorine atoms in FeCl3, calculate the total oxidation state contributed by chlorine: 3 * (-1) = -3.
  • Step 4: To find the oxidation state of iron (Fe), set up the equation: oxidation state of Fe + total oxidation state of Cl = 0.
  • Step 5: Substitute the values into the equation: oxidation state of Fe - 3 = 0.
  • Step 6: Solve for the oxidation state of Fe: oxidation state of Fe = +3.
