Answer 1

explain laboratory and industrial preparation of

hydrogen

In the laboratory, H2 is usually prepared by the reaction of acids on metals such as zinc with Kipp's apparatus. Zn + 2 H+ -- Zn2+ + H2 Aluminium can also produce H2 upon treatment with bases: 2 Al + 6 H2O + 2 OH− -- 2 Al(OH)−4 + 3 H2 The electrolysis of water is a simple method of producing hydrogen.
