Question

some chemical reactants are listed in the table below. complete the table by filling in the oxidation state of the highlighted atom. species oxidation state of highlighted atom fe³⁺(aq) cl₂(g) h₃o⁺(aq) nh₄⁺(aq)

Explanation:

Step1: Determine oxidation state of Fe³⁺

The ion is Fe³⁺, so oxidation state is +3.

Step2: Determine oxidation state of Cl₂

In elemental form, oxidation state of Cl in Cl₂ is 0.

Step3: Determine oxidation state of H in H₃O⁺

Let oxidation state of H be x. Oxygen has - 2 oxidation state and overall charge is +1. So, 3x+( - 2)=+1, solving gives x = +1.

Step4: Determine oxidation state of N in NH₄⁺

Let oxidation state of N be y. Hydrogen has +1 oxidation state and overall charge is +1. So, y + 4×(+1)=+1, solving gives y=-3.

Answer:

species	oxidation state of highlighted atom
Cl₂(g)	0
H₃O⁺(aq)	+1
NH₄⁺(aq)	- 3
