STANDARD Chemistry Oxidation State MCQ Question
The charges x and y on the following ions are (i) [Co(NH₃)₂Cl₄]ˣ (ii) [Fe(CN)₆]ʸ (Oxidation state of Co is +3 and Fe is +2 in their respective complexes.)
x = +1, y = −1
x = −1, y = +3
x = −1, y = −4
x = −2, y = −3
Correct Answer
Detailed Explanation
In [Co(NH₃)₂Cl₄]ˣ, the oxidation state of Co is +3. Hence, x = +3 + 2 × 0 + 4 × (−1) = −1. In [Fe(CN)₆]ʸ, the oxidation state of Fe is +2. Hence, y = +2 + 6 × (−1) = −4.
