Question

Copper does not liberate hydrogen on reacting with dilute H2SO4​

Answer 1

Answer:

Copper does not react with dilute sulphuric acid, liberating hydrogen because copper is lower in electromotive series than hydrogen, or more fundamentally, because the magnitude of change in gibbs free energy when a single atom of elemental hydrogen ionizes is greater than the magnitude of the change in gibbs free ...

please give me 10 thanks please

Answer 2

Answer:

Copper does not react with dilute sulphuric acid, liberating hydrogen because copper is lower in electromotive series than hydrogen, or more fundamentally, because the magnitude of change in gibbs free energy when a single atom of elemental hydrogen ionizes is greater than the magnitude of the change in gibbs free energy when a single atom of elemental copper ionizes. Therefore , elemental copper does not have a sufficient chemical potential to liberate elemental hydrogen from compounds in which hydrogen has a oxidation state of +1.
