Step 1: Understand the composition of . In the compound , we have: - 2 hydrogen atoms ( ), - 1 sulfur atom ( ), - 4 oxygen atoms ( ). Step 2: Assign oxidation states. - The oxidation state of hydrogen ( ) is . - The oxidation state of oxygen ( ) is . Step 3: Set up the equation for the oxidation state of sulfur. The sum of the oxidation states in a neutral compound is zero. Let the oxidation state of sulfur be . For , the equation becomes: Simplifying: Answer: Therefore, the oxidation state of sulfur in is .
