QAIPMT-2002-Ch-2765: NEET 2002 Chemistry - Class 12 AIPMT-2002-Ch-2765 Solution: In electrolysis of NaCl when Pt electrode is taken then \(H_2\) …

In electrolysis of NaCl when Pt electrode is taken then H2H_2 is liberated at cathode while with Hg cathode it forms sodium amalgam

Multiple Choice Options

  • A Hg is more inert than Pt
  • B More voltage is required to reduce H+H^+ at Hg than at Pt
  • C Na is dissolved in Hg while it does not dissolve in Pt
  • D Conc. of H+H^+ ions is larger when Pt electrode is taken.

Step-by-Step Verified Solution

In electrolysis of NaCl when Pt electrode is taken then H 2 liberated at cathode while with Hg cathode it forms sodium amalgam because more voltage is required to reduce H + at Hg than Pt.
