Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. +2
  2. +3
  3. +4
  4. +6

Correct answer and explanation

Correct answer: +3

Explanation: āœ… Correct Answer: B) +3 šŸ“š Explanation: In the coordination compound Potassium ferricyanide, there are three potassium ions (K+) contributing a +3 charge. To balance the complex anion [Fe(CN)6]3-, we note that each cyanide (CN-) ligand carries a -1 charge. Therefore, x + 6(-1) = -3, meaning the oxidation state of iron (x) is +3.
