Question

What happens when dilute sulphuric acid and dilute hydrocholric acid are treated with metals placed above hydrogen in the activity series of metals ?​

Answer 1

Answer:

with dilute sulfuric acid and dilute hydrochloric acid. It is dangerous to put these metals into an acid. The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H2(g).

Question

What happens when dilute sulphuric acid and dilute hydrocholric acid are treated with metals placed above hydrogen in the activity series of metals ?

Answer

◇The surface of metallic lead is protected by a thin layer of lead oxide PbO.

◇This renders the lead essentially insoluble in sulfuric acid.

◇Lead reacts slowly with hydrochloric acid and nitric acid.

◇With dilute sulfuric acid and dilute hydrochloric acid.

◇It is dangerous to put these metals into an acid.

◇The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H2(g).
