Yes, lead does react with certain acids, although its reactivity can vary significantly depending on the specific acid.
While metallic lead's surface is typically covered by a protective layer of lead oxide (PbO), this layer doesn't render it inert to all acidic conditions.
Lead's Interaction with Different Acids
Based on the provided information, we can understand how lead behaves when exposed to various common acids:
- Sulphuric Acid: The protective layer of lead oxide makes lead essentially insoluble in sulphuric acid. This property historically made lead a useful material for containers storing this acid.
- Hydrochloric Acid (HCl): Lead reacts slowly with hydrochloric acid.
- Nitric Acid (HNO3): Lead reacts slowly with nitric acid.
Summary of Lead Reactivity with Acids
Here's a quick overview of lead's reaction with the acids mentioned:
| Acid | Reaction Outcome | Key Factor Mentioned |
|---|---|---|
| Sulphuric Acid | Essentially insoluble | Protective PbO layer |
| Hydrochloric Acid | Reacts slowly | |
| Nitric Acid | Reacts slowly |
This shows that although lead is notably resistant to sulphuric acid due to its oxide coating, it is not immune to all acids and will undergo slow reactions with hydrochloric and nitric acids.
