Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the search-in-place domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

Laboratory Preparation of Hydrogen — Chemistry Keypoint

Laboratory Preparation of Hydrogen

It is prepared by the action of a mineral acid on metals (those higher than hydrogen in the electrochemical series).

e.g.

Zn(s) + 2HCL(aq)    →    ZnCL2(aq) + H2(s)

Industrially, hydrogen is produced by the Bosch process and electrolysis.
