Explanation:
The solubility of lead oxide in dilute sulfuric acid is also very low. When lead oxide is added to dilute sulfuric acid, a thin layer of lead sulfate is formed on the surface of the solid lead oxide. This layer protects the rest of the lead oxide from getting converted to lead sulfate in what is known as passivation.
