Question

lead carbonate does not react with dilute hcl

Answer 1

Lead is resistant to hydrochloric acids as well as sulfuric acid. Lead appears not to react with dilute hydrochloric acid and dilute sulphuric acid.This is because a layer of lead (II) chloride or lead (II) sulphate is formed from the initial reaction between the lead and the dilute acid. This layer is insoluble in water and quickly forms a coating around the metal. The coating protects metal from further attack by acids.

Answer 2

Lead does not react with diluted hydrochloric acid and diluted sulphuric acid because the initial reaction between lead and diluted acid form a thin layer of lead (II) chloride or lead (II) sulphate.

These of lead (II) chloride or lead (II) sulphate layer is water-insoluble and forms a white colour layer on the surrounding of the metal.

If we proceed with the reaction between lead and hydrogen chloride, there occurs only slight reaction and forms a precipitate which is lies on the surface of the lead metal.

Hence, no reaction occurs.
