The correct Answer is:
To determine the change that occurs when lead monoxide (PbO) is converted into lead nitrate (Pb(NO3)2), we need to analyze the oxidation states of lead in both compounds. ### Step 1: Identify the oxidation state of lead in lead monoxide (PbO) - In lead monoxide (PbO), let the oxidation state of lead be \( X \). - The oxidation state of oxygen is \(-2\). - The compound is neutral, so the sum of the oxidation states must equal zero: \[ X + (-2) = 0 \] \[ X = +2 \] - Therefore, the oxidation state of lead in PbO is +2. ### Step 2: Identify the oxidation state of lead in lead nitrate (Pb(NO3)2) - In lead nitrate (Pb(NO3)2), let the oxidation state of lead again be \( X \). - The nitrate ion (NO3) has an oxidation state of \(-1\) and there are 2 nitrate ions in the compound: \[ X + 2(-1) = 0 \] \[ X - 2 = 0 \] \[ X = +2 \] - Therefore, the oxidation state of lead in Pb(NO3)2 is also +2. ### Step 3: Compare the oxidation states - The oxidation state of lead in both lead monoxide and lead nitrate is +2. - Since there is no change in the oxidation state of lead during the conversion from PbO to Pb(NO3)2, we conclude that there is neither oxidation nor reduction. ### Conclusion The change that occurs when lead monoxide is converted into lead nitrate is **neither oxidation nor reduction**.
