Text Solution

AI Generated Solution

To determine the role of \( H_2O_2 \) in the reaction \( PbS(s) + 4H_2O_2(aq) \rightarrow PbSO_4(s) + 4H_2O(l) \), we need to analyze the oxidation states of the elements involved in the reaction. ### Step 1: Identify the oxidation states - **Lead (Pb)** in \( PbS \): The oxidation state of Pb is +2. - **Sulfur (S)** in \( PbS \): The oxidation state of S is -2. - **Oxygen (O)** in \( H_2O_2 \): The oxidation state of O in \( H_2O_2 \) is -1. - **Lead (Pb)** in \( PbSO_4 \): The oxidation state of Pb remains +2. - **Sulfur (S)** in \( PbSO_4 \): The oxidation state of S is +6. ...
