Question

Why does not silver liberate hydrogen on reacting with dilute hydrochloric acid?​

Answer 1

Answer:

Silver is placed below hydrogen in the reactivity series as we know. Therefore, it cannot lose electrons to hydrogen ions of the acid called dilute hydrochloric acid. Hydrogen gas is not evolved when silver reacts with dilute hydrochloric acid.

Answer 2

Answer: No change takes place because silver metal categorized as noble metal and does not react with hydrochloric acid in normal situations. The temperature of the reaction mixture rises when aluminium (Al) is added.
