Question

nitric acid is oxidizer and it's process with pbo but why it's not processing with pbo2?​

Answer 1

Answer:

PbO is a basic oxide and simple acid base reaction takes place between PbO and HNO3. On the other hand in PbO2 lead is in + 4 oxidation state and cannot be oxidised further. Therefore no reaction takes place. Thus, PbO2 is passive, only PbO reacts with HNO3.

Answer 2

Answer:

hope this helps

Explanation:

Nitric acid is an oxidizing agent and reacts with PbO to give a simple acid- base reaction without any change in oxidation state. In PbO2, Pb is in +4 oxidation state and cannot be oxidized further, hence no reaction takes place between PbO2 and HNO3.
