## Determining Oxidation States

In this exercise, we need to determine the oxidation state for each of the elements listed below:

1. **Carbon in Carbon Monoxide (CO):**
- The oxidation state of carbon in carbon monoxide (CO) is displayed as **+2**.

2. **Chlorine in Hypochlorite Ion (ClO⁻):**
- The oxidation state of chlorine in the hypochlorite ion (ClO⁻) needs to be determined.

3. **Sulfur in Sulfurous Acid (H₂SO₃):**
- The oxidation state of sulfur in sulfurous acid (H₂SO₃) needs to be determined.

### How to Proceed

- Use reference materials to assist with determining oxidation states if needed.
- Select the appropriate oxidation state for chlorine and sulfur from the options provided.

### Navigation

- Click "Submit Answer" after choosing the oxidation states.
- If needed, click "Retry Entire Group" to attempt the questions again.
- Note: You have 9 more group attempts remaining.

This exercise helps in understanding the concept of oxidation states and their application in chemical compounds and ions.

Expert Solution

Step 1

Oxidation number:

• Oxidation number of atoms in pure element or Atoms in free or uncombined elements is 0 (zero).

• oxidation number of oxygen usually -2 in most of its compound except in case of H2O2 (peroxide) where its oxidation number is -1, KO2 (superoxide) where its oxidation number is - 1/2 and OF2 where its oxidation number is + 2.

• sum of oxidation in the neutral compound is zero

• oxidation number of the monoatomic ions is equal to the charge on the ions.

• oxidation number of halogen is usually -1.

• oxidation number of atoms in the polyatomic ion is equal to the sum of the charge on the ion.
