What is the oxidation state of cobalt in the [Co(NH₃)₄Cl₂]⁺ complex ion?

Question

Quizplus · Accepted Answer

By analyzing the formula, we can see that there are six coordinating atoms directly surrounding the cobalt ion, which are four sulfur atoms, one nitrogen atom, and one chloride atom. Each sulfur atom has a -2 oxidation state, the nitrogen atom has a -3 oxidation state, and the chloride atom has a -1 oxidation state. Since the overall charge of the complex is +1, we can set up the equation:

x + (-3) + 4(-2) + (-1) = +1

Simplifying this equation, we get:

x - 12 = +1

x = +3

Therefore, the oxidation state of cobalt in the complex ion is +3, which corresponds to Choice C.
