1.	In electrolysis of `NaCl` when `Pt` electrode is taken `H_(2)` is liberated at cathode while `Hg` cathode it forms sodium amalgam becauseA. Hg ismore inert than PtB. More voltage is required to reduce `H^(+)` at Hg than at Pt.C. Na is dissolved in Hg while it does not dissolve in PtD. Conc. Of `H^(+)` ions is larger when Pt electrode is taken.
Answer» Correct Answer - B More voltage is required to reduc e `H^(+)` at Hg than at Pt.
