Question

Assertion \((A) :\) Some metals like platinum and palladium, can be used as storage media for hydrogen.

Reason \((R) :\) Platinum and palladium can absorb large volumes of hydrogen.

Answer 1

Some metals like platinum and palladium can be used as storage media for hydrogen due to following reasons:

\(1)\) These metals are inert and could not react with the atomic hydrogen.

\(2)\) Because of the high surface area, these metals allow hydrogen to get adsorbed over their surface and thus can absorb large volumes of hydrogen.

Therefore, assertion and reason both are correct and reason is the correct explanation of assertion. Hence, option \((A)\) is correct.
