Metallic hydrides are useful for hydrogen storage because

A

they reacts with hydrogen and form stable compound

B

they absorb H-atoms

C

they adsorb H-atoms

D

they form unstable compounds

Text Solution

Verified by Experts

The correct Answer is:
C
In metallic hydrides, hydrogen is adsorbed as H atoms. This property of adsorption of hydrogen on transition metals is widely used as its storage media. Some of the metals such as Pd, Pt can accommodate a very large volume of hydrogen. This property has high potential for hydrogen storage and as a source of energy. Metallic hydrides on heating decompose to form hydrogen and very finely divided metal.
