Describe the reactions of dilute sulphuric acid with oxides and hydroxides.

Describe the reactions of dilute sulphuric acid with oxides and hydroxides.

---

- Reacts to form salt and water.
- However, those metal oxides whose sulphates are insoluble react only for a while.
- Thus reaction between dilute sulphuric (VI) acid and lead (II) oxide stops almost immediately.
- This is due to formation of an insoluble layer of lead (II) sulphate which effectively prevents further contact between acid and oxide.
