JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Very pure hydrogen(99.9%) can be made by which of the following processes?

(A)Mixing natural hydrocarbons of high molecular weight
(B)Electrolysis of waterCorrect
(C)Reaction of salt like hydrides with water
(D)Reaction of methane with steam

Answer: (B)

Solution

Electrolysis of water gives very pure hydrogen gas (up to 99.9% or higher purity) since it is produced directly from water with no carbon-containing by-products. Steam reforming of methane (D) and other hydrocarbon-based processes yield
