Question: Dihydrogen of high purity $(>99.95 \%)$ is obtained through:
the electrolysis of warm $\mathrm{Ba}(\mathrm{OH})_{2}$ solution using Ni electrodes.
the reaction of $\mathrm{Zn}$ with dilute $\mathrm{HCl}$
the electrolysis of brine solution.
the electrolysis of acidified water using Pt electrodes.
Correct Option: 1
Solution:
High purity $(>99.95 \%)$ dihydrogen is obtained by electrolysing warm aqueous barium hydroxide solution between nickel electrodes.
